Customer support leaders have rarely had more pressure—or more opportunity. Legacy button-based chatbots are frustrating customers and your team, but ripping them out overnight risks broken journeys, missed SLAs, and angry stakeholders. Done well, though, moving to a modern AI support assistant can lower costs, improve CSAT, and make your agents’ jobs meaningfully better.

This guide walks through a practical, end-to-end migration path: from auditing your existing bot and mapping intents, to running AI in shadow mode, planning a staged rollout, and tuning post-launch—without breaking customer experience.

---

Why It’s Time to Move Beyond Button-Based Chatbots

The stakes for getting this right are high. PwC found that 32% of customers would stop doing business with a brand they love after just one bad experience (source). When you’re touching thousands of conversations a day through automation, a clumsy migration can become very expensive, very fast.

At the same time, customer expectations and technology have both moved on:

• Experience is now as important as the product. Salesforce reports that 88% of customers say the experience a company provides is as important as its products or services (source). Your chatbot is no longer a sidecar; it is part of the product.
• Generative AI is becoming standard in service. Gartner predicts that by 2026, around 80% of customer service and support organizations will be applying generative AI in some form (source). Standing still with an old rules engine means falling behind.
• The economic upside is significant. McKinsey estimates generative AI can drive a 30–45% productivity uplift in customer operations by drafting responses, summarizing contacts, and handling routine queries end-to-end (source).

Button-based chatbots were built for a world of narrow FAQs and predictable flows. Today’s customers expect natural conversation, fast resolution, and effortless escalation to a human when needed. Modern AI assistants can meet that bar—but only if you migrate thoughtfully.

---

Common Failure Modes of Legacy Chatbots (and How AI Fixes Them)

Before designing your next-generation assistant, get clear on why the old one is underperforming. Common issues include:

1. High customer effort and dead ends

Gartner has warned that poorly designed chatbots can increase customer effort and drive disloyalty—especially when they misinterpret intent or trap users in dead-end flows without a graceful handoff to live agents (source). Symptoms:

• Customers clicking through multiple menus and still not finding the right option.
• Loops like “Did this answer your question? → No → Restart → Same options.”
• No obvious “talk to a human” path.

Modern AI assistants:

• Understand free-form language (“I was double charged last month, can you fix it?”) instead of relying solely on rigid buttons.
• Can detect frustration and confusion (repeated rephrasing, “agent”, “help”, “complaint”) and proactively escalate.
• Provide graceful fallback: “I’m not confident I can solve this. Let me bring in a human.”

2. Fragile, scripted flows that break off the happy path

Forrester described many early customer-service chatbots as “glorified FAQs” that fail as soon as customers move off the happy path, leading to low containment and poor satisfaction (source).

Typical patterns:

• Flows assume perfect user behavior (“First select product, then issue, then sub-issue…”).
• Slightly unexpected questions (“My shipment is late and my address changed”) can’t be handled.
• Small product changes require manual updates across dozens of nodes.

Modern AI assistants:

• Generalize across phrasing and can handle multi-intent utterances (“delivery late + change address”).
• Pull from shared knowledge and policies instead of duplicating text across flows.
• Are easier to update: you change a policy document once, and the assistant immediately answers with the new rule (if it uses retrieval from your knowledge base).

3. Poor personalization and context

Legacy bots often treat every message in isolation:

• They forget context across turns (“What was my order number again?”).
• They don’t leverage account data, history, or channel context.
• Handoffs to agents lose the entire conversation.

AI-based systems can:

• Maintain conversational context over many turns.
• Personalize answers based on user type, plan, region, or past activity.
• Pass rich transcripts and summaries to agents so customers don’t have to repeat themselves.

Your migration goal is not just to “swap engines” but to eliminate these failure modes in the new architecture.

---

Step 1: Audit Your Existing Chatbot Flows, Content & Entry Points

Before you touch AI, treat your current chatbot as a system to be reverse engineered. You need a clear view of what it does today—and where it’s failing—so you don’t blindly recreate existing problems.

1. Inventory all entry points

List every surface where customers encounter your bot:

• Website (home, pricing, checkout, account pages)
• In-app widgets (web and mobile)
• Help center and “Contact us” pages
• In-product banners or nudges
• Embedded chat in emails or SMS flows

For each, note:

• Who sees it (prospects vs customers, logged-in vs anonymous, geography).
• What the current promise is (“Ask me anything”, “I can help with billing & orders”, etc.).
• How easy it is to reach a human from that entry point.

This becomes your “surface map” for the staged rollout later.

2. Export and analyze conversation logs

Pull at least 3–6 months of data from your existing bot and support channels:

• Chatbot transcripts
• Live chat logs
• Email tickets (subject + body)
• Phone call summaries (if available)

Google Cloud’s Dialogflow CX best-practices guide emphasizes starting from real transcripts to identify top intents and contact drivers, rather than inventing flows from scratch (source). Follow that advice:

• Cluster conversations into themes: account access, payment issues, shipping, product how-tos, bugs, etc.
• Identify the top 20–30 intents by volume.
• Mark where the current chatbot:
  • Contains the issue end-to-end.
  • Transfers to an agent.
  • Fails (user abandons, loops, or leaves negative feedback).

3. Document current flows and decision trees

If you can, export a visual representation of your bot’s flows. If not, manually map the major ones:

• Start from each entry point and click through every path.
• Note:
  • Number of steps to reach common outcomes.
  • Where branches explode in complexity.
  • Where content (FAQ answers) is duplicated.

Tag flows as:

• High volume, low complexity (prime candidates for early AI automation).
• High volume, high complexity (good for AI-assisted agents first).
• Low volume, high risk (likely to stay human-first).

4. Collect existing content the bot depends on

Gather:

• Knowledge base / help center articles
• Saved replies or macros
• Internal policy docs and SOPs
• Product documentation and release notes

You’ll clean and restructure these in Step 3, but you need them inventoried now.

Deliverable for Step 1:

• A list of entry points and promises.
• A ranked list of intents by volume and friction.
• A map of current flows and where they succeed/fail.
• An inventory of knowledge sources.

This is your baseline. It will guide what to automate first and where to be most cautious.

---

Step 2: Classify Intents and Outcomes Instead of Scripts

Legacy bots are built around scripts: “If user clicks A, show message B, then offer C or D.” Modern AI support requires you to think in terms of intents, entities, and outcomes.

IBM’s guidance on building virtual agents stresses mapping intents and dialog flows from real support data, and iterating based on analytics, rather than relying purely on speculative journeys (source).

1. Define your core intents

From your audit, define a clear intent taxonomy. For example:

• Authentication & Access
  • Reset password
  • Can’t log in (2FA issue, locked account)
• Billing & Payments
  • Update payment method
  • Dispute a charge
  • Request invoice / receipt
• Orders & Shipping
  • Where is my order?
  • Change shipping address
• Product Usage
  • How to set up [Feature]
  • Troubleshooting [Error code]

For each intent, gather:

• Example customer phrases from logs (“My card was charged twice”, “Invoice for June?”).
• Key entities needed to resolve (order ID, email, plan type).
• Related policies or constraints (SLAs, refund rules, compliance).

2. Attach outcomes, not just responses

An intent is not just an answer; it’s an outcome. Define what “done” means:

• Self-serve resolution
  Example: “Reset password” → password reset email sent; user can log in.

• Assisted resolution
  Example: “Complex billing dispute” → case created with the right priority/tags and routed to the right queue with all necessary details.

• Information-only
  Example: “What are your business hours?” → user receives accurate, localized info.

Document for each intent:

• Preferred outcome(s).
• Whether AI can complete the outcome autonomously (e.g., via API calls) or should only collect info and route.
• Any hard “do not automate” constraints (e.g., cancellations in some markets).

3. Risk-tier your intents

Classify each intent into risk tiers:

• Tier 1: Safe to automate

  • High volume, low risk (password resets, order status, basic how-tos).
  • Clear policies, little room for interpretation.

• Tier 2: AI-assisted, human-in-the-loop

  • AI drafts responses or gathers info; human reviews/sends.
  • Used for nuance-heavy scenarios (discount negotiations, complex technical issues).

• Tier 3: Human-only

  • Legal, compliance, or high-financial-impact conversations.
  • VIP complaints, press inquiries, regulator contacts.

Your tiers will drive where you allow full AI automation vs draft-mode vs no AI at all.

4. Move from node trees to an intent library

Your goal is to replace sprawling scripts with a structured intent library, where each entry includes:

• Intent name and description
• Example phrases
• Required and optional entities
• Outcome(s) and business rules
• Risk tier and escalation rules
• Linked knowledge sources (articles, SOPs)
• Supported channels

This becomes the backbone of your AI assistant and simplifies ongoing maintenance.

---

Step 3: Prepare Your Knowledge Sources for an AI-First World

An AI support assistant is only as good as the knowledge it can access. If your content is outdated, inconsistent, or scattered, even the best model will fail.

1. Recognize how central self-service already is

Microsoft’s Global State of Customer Service report found that 90% of consumers expect brands to offer online self-service and 66% try self-service first before contacting a live agent (source). Yet most organizations still see low self-service success.

Gartner has repeatedly observed that while most customers begin in self-service, only about 10–15% successfully resolve their issue without assisted service, largely due to gaps in knowledge quality and findability (source). This is exactly the problem you must solve before you point AI at your content.

2. Inventory and centralize knowledge

Gather all content that might answer customer questions:

• Public help center and FAQs
• Community posts (curated, not the whole forum)
• Internal knowledge base / wiki
• Agent macros and saved replies
• Product and API docs
• Policy and legal documents
• Training decks and playbooks

Decide which of these should be:

• Customer-facing (safe for the AI to quote directly).
• Agent-facing only (used for AI-assisted agents, not directly for customers).

3. Improve quality and structure

Review top-used and top-intent-related content first:

• Make answers specific and action-oriented.
• Use clear headings, short paragraphs, and bullet lists.
• Include explicit preconditions (“To do this you must be logged in as…”).
• Remove conflicting or duplicate information.
• Add “last reviewed” dates and owners.

This isn’t just content hygiene; it directly impacts AI answer quality.

4. Fill content gaps

From your intent analysis, identify:

• High-volume intents with no good knowledge articles.
• Outdated policies or features that aren’t documented.
• Edge cases that frequently reach Tier 2/3 support.

Prioritize creating or updating content for:

• Top 20–30 intents by volume.
• Intents you plan to automate in your first AI phase.

5. Adopt knowledge-centered practices

The Consortium for Service Innovation’s research on Knowledge-Centered Service (KCS®) shows that organizations who systematically capture and reuse knowledge as part of case work see:

• 50–60% improvements in time to proficiency for new agents.
• 30–50% increases in self-service success.
• 5–10% increases in CSAT (source).

Those benefits map directly to AI readiness: strong, up-to-date knowledge makes your assistant more accurate and your agents more effective when AI drafts answers.

Even if you don’t adopt full KCS, implement simple practices:

• Every resolved case should either reuse or improve a knowledge article.
• Agents should flag gaps and inaccuracies in a lightweight way.
• Content owners should review high-traffic articles regularly.

6. Prepare content for machine consumption

For AI retrieval to work well:

• Ensure content has consistent structure (titles, sections, FAQs).
• Tag documents with metadata:
  • Product/feature
  • Region and language
  • Plan/segment (SMB vs enterprise)
  • Audience (customer vs internal)
• Remove or mask sensitive data (PII, secrets, internal-only URLs) from anything that might feed the customer-facing assistant.

This is where you turn a traditional knowledge base into a high-quality “source of truth” the AI can safely draw from.

---

Step 4: Design the New Experience: AI Assistant, Fallbacks & Escalations

With intents and knowledge in place, you can design the end-to-end experience of your AI assistant—not just what it says, but how it behaves.

1. Use retrieval-augmented generation (RAG) as your default pattern

Rather than letting an AI model answer purely from its general training, modern best practice is retrieval-augmented generation (RAG): the assistant first retrieves relevant documents from your curated knowledge and then generates an answer based only on those documents.

OpenAI recommends this approach for enterprise chatbots because it reduces hallucinations and allows precise control over what the bot “knows” (source). For your migration, this means:

• The assistant answers based on your help center, policies, and docs—not the open internet.
• You can audit and improve answers by looking at which sources were retrieved.
• Regulatory or policy changes take effect as soon as you update your content.

2. Be transparent and keep humans easily reachable

The Capgemini Research Institute found that while consumers appreciate AI making interactions faster, they expect transparency about when they’re interacting with AI and want easy access to humans, especially for complex or sensitive issues (source).

Design your experience accordingly:

• Clearly label the assistant as an AI (e.g., “Virtual assistant”).
• Set expectations: what it can and cannot do (e.g., “I can help with most how-to and account questions, but I’ll connect you to a person for billing disputes or cancellations.”).
• Always show a visible option to reach a human—don’t hide it behind multiple clicks.

3. Define interaction patterns

Core patterns to design:

• Free-text first, smart suggestions second
  Let users type in their own words, but offer quick-reply suggestions based on common intents and current context.

• Smart forms when structure matters
  For flows that require specific data (e.g., refunds, identity verification), the AI can introduce a structured form mid-conversation so agents and back-office systems get clean inputs.

• Multi-intent handling
  Design for users who ask for multiple things at once (“Change my address and pause my subscription”). Decide whether the assistant handles one at a time or in parallel, and how it communicates that.

4. Fallbacks and guardrails

Define what the assistant should do when:

• Confidence in its answer is low.
• It has asked for information twice and still doesn’t have what it needs.
• The user appears frustrated or types “agent” / “human”.

Typical behaviors:

• Acknowledge the limitation and offer immediate escalation:
  “I’m not confident I can solve this correctly. Let me bring in a specialist.”

• Offer alternative channels (email, callback) if chat is saturated or off-hours.

• Log these cases for review—they’re gold for improving knowledge and intent handling.

5. Handoff design

When escalating:

• Pass the full conversation history and any structured data already collected.

• Include a brief AI-generated summary to speed up agent ramp-up:

  • Issue
  • Steps already taken
  • Customer sentiment
  • Suggested next actions (clearly labeled as AI suggestions)

• Let the customer know what’s happening (“Connecting you to a human…”, with expected wait time).

A smooth handoff is critical to preserving trust during and after your migration.

---

Step 5: Run AI in Shadow Mode to De-Risk the Migration

You don’t have to (and shouldn’t) flip the switch from legacy bot to AI assistant in one go. Use shadow mode—a well-established technique in machine learning—to validate performance safely.

1. What is shadow mode?

In shadow mode, the new AI assistant:

• Receives the same inputs as your existing bot or human agents.
• Generates proposed answers and actions.
• Does not show them to customers or take real actions.
• Logs everything for offline analysis.

Stripe describes using this pattern when deploying new fraud models: models run “in shadow,” making predictions and logging outputs under real traffic without affecting users until their performance is validated (source).

Google’s Site Reliability Engineering practices also recommend dark launches and canary releases—running new systems in parallel and gradually increasing their real traffic share once they’ve proven themselves (source).

The NIST AI Risk Management Framework explicitly encourages organizations to pilot AI systems in controlled environments, evaluate them against defined metrics, and continuously monitor them before and after deployment (source). Shadow mode is how you do that in support.

2. How to run shadow mode in practice

Options:

• Agent-assist shadowing

  • Agents handle conversations as usual.
  • The AI assistant silently drafts responses and suggested actions in a side panel.
  • Agents ignore these drafts at first; you just log them and compare.

• Legacy bot shadowing

  • Customers continue to see the old bot’s outputs.
  • The new AI assistant generates alternative answers for the same inputs, which are stored for offline comparison.

In both cases, capture:

• AI-generated response.
• Human/legacy-bot response.
• Final outcome (resolved, escalated, reopened).
• Relevant metadata (intent, channel, customer segment).

3. What to measure in shadow mode

For each intent and channel, compare AI answers to your baseline on:

• Accuracy and policy compliance

  • Are AI responses factually correct given your knowledge base?
  • Do they follow current policies and tone guidelines?

• Completeness

  • Would the AI’s answer have resolved the issue without additional back-and-forth?

• Risk indicators

  • Any hallucinations or made-up policies?
  • Any security/privacy concerns (e.g., oversharing internal details)?

• Efficiency potential

  • For simple intents, how often is the AI answer as good as or better than the agent’s?
  • For complex intents, does the AI produce useful drafts/summaries?

Define thresholds for moving an intent from “shadow” to “live autopilot” (e.g., 95%+ of answers judged correct and safe in review).

4. Use findings to refine

Shadow mode should:

• Reveal knowledge gaps (AI can’t answer because the content doesn’t exist or is ambiguous).
• Surface ambiguous intents that need clearer definitions or features.
• Help you tighten guardrails for high-risk categories.

Only once you’re confident on specific intents and surfaces do you start exposing AI answers to customers.

---

Step 6: Plan a Staged Rollout (Routes, Segments, and Channels)

With validated performance in shadow mode, you can plan a phased rollout. The goal: realize benefits quickly on safe surfaces while minimizing risk.

Zendesk’s CX Trends 2023 report found that most CX leaders view AI as essential to staying competitive and plan to expand AI across more touchpoints—not just front-door triage (source). A staged plan sets you up for that expansion without a “big bang” cutover.

1. Choose your first surfaces

Prioritize combinations of:

• Low risk (Tier 1 intents).
• High volume (meaningful impact).
• Clean data and journeys (fewer unknowns).

Common starting points:

• Logged-in web app users in a single language.
• Help center widget for “how-to” and account questions.
• Business-hours traffic (when agents are available as backup).

Avoid leading with:

• Anonymous visitors with high fraud risk.
• Highly regulated markets or segments.
• Edge-case-heavy channels (e.g., specific B2B queues) until later.

2. Roll out by dimension

You can stage by:

• Intent

  • Start with 5–10 Tier 1 intents in autopilot.
  • Keep everything else on legacy bot or human-first, even in the same channel.

• User segment

  • Begin with internal staff or beta customers.
  • Then expand to specific regions or plan types.

• Channel

  • Start with web chat.
  • Add in-app, then email auto-drafts, then other channels.

3. Control exposure and fallbacks

Use feature flags or routing rules to:

• Direct a small percentage of eligible traffic (e.g., 10–20%) to the new AI assistant initially.
• Automatically fall back to human chat when:
  • The AI hits a confidence threshold.
  • The user requests an agent.
  • The issue matches a Tier 2/3 intent.

Monitor metrics (next section) closely and adjust routing rules weekly in the early phases.

---

Step 7: Define Success Metrics and Build a Migration Scorecard

Without clear metrics, it’s easy for an AI migration to “optimize” for the wrong thing—like deflecting tickets at the expense of customer loyalty.

1. Core metrics to track

The International Customer Management Institute (ICMI) notes that CSAT, service level, and first-contact resolution are among the most widely used—and important—contact center metrics (source). Those should remain central.

Add metrics tailored to AI support. Zendesk’s guidance on customer service metrics emphasizes self-service success, bot containment, and handoff rates as key indicators for chatbot performance (source).

Your migration scorecard should include:

Experience metrics

• CSAT (overall and AI-specific)
• NPS (if used)
• Customer Effort Score (CES)—“How easy was it to resolve your issue?”
• Complaint rate and negative feedback themes

Operational metrics

• First Contact Resolution (FCR)
• Average Handle Time (AHT)
• Average Resolution Time
• Service Levels (e.g., chat answered within 30 seconds)

Automation metrics

• Containment/automation rate (conversations fully resolved by AI)
• Bot → agent handoff rate
• Fallback rate (AI admits it can’t help)
• Percentage of AI answers edited by agents (for AI-assisted scenarios)

2. Explicitly measure customer effort

Research published in Harvard Business Review found that reducing customer effort is more strongly correlated with loyalty than delighting customers, and high-effort interactions significantly increase churn and negative word-of-mouth (source).

To avoid “breaking CX” during migration, track effort proxies:

• Number of steps (messages, clicks) to resolution.
• Number of transfers between bot and agents.
• Rate of channel-switching (chat → email → phone for the same issue).
• Repeat contact rate within 7–14 days.

Make sure AI-driven flows reduce these numbers relative to your baseline.

3. Build an intent-level scorecard

For each major intent, track:

• Volume
• Automation/containment rate
• CSAT and CES for AI vs human-handled conversations
• Escalation and error rates
• Policy/compliance incident rate (if applicable)

Define criteria for:

• Promoting an intent to autopilot (e.g., AI CSAT ≥ human CSAT, containment ≥ 60%, low error rate).
• Demoting an intent (e.g., sharp drop in CSAT, spike in escalations, early signs of hallucinations or compliance issues).

Use this scorecard in weekly or biweekly reviews with stakeholders during rollout.

Handling Edge Cases: Compliance, VIPs, and High-Risk Conversations

AI’s flexibility is a double-edged sword. Without guardrails, a model can produce confident-sounding but wrong answers—dangerous in high-stakes scenarios.

Stanford HAI notes that large language models can generate plausible-sounding but incorrect or fabricated information, especially on niche topics or where training data is sparse (source). OpenAI likewise recommends limiting models to vetted knowledge and using human oversight for high-stakes domains (source).

1. Identify your high-risk categories

Common high-risk buckets:

• Legal, compliance, or regulatory questions
• Financial decisions (credits, refunds beyond policy, pricing exceptions)
• Healthcare or safety guidance
• Security and privacy (account takeovers, data requests)
• VIP accounts, strategic customers, or press

Map which intents fall into these categories and explicitly mark them as Tier 2 or Tier 3 (from earlier).

2. Define AI behavior by risk tier

• Tier 1 (safe)

  • AI can answer autonomously and perform allowed actions (e.g., via APIs).
  • Still logs everything for review.

• Tier 2 (assisted)

  • AI can draft responses and suggest actions.
  • Human must approve before sending or executing.

• Tier 3 (human-only)

  • AI can help agents by summarizing the context or surfacing relevant docs.
  • It should not interact directly with the customer or take actions.

Implement technical enforcement: for Tier 2/3 queues, your system should simply not allow direct AI responses to be sent without approval.

3. VIP and special-handling rules

Define special handling for:

• High-value customers (based on plan, revenue, or relationship).
• Certain geographies with stricter regulations.
• Specific partners or internal stakeholders.

Typical pattern:

• AI recognizes the account as VIP from your CRM.
• It immediately offers escalation to a specialized queue.
• It may still summarize and assist the agent, but acts conservatively with direct responses.

4. Content and compliance controls

• Exclude certain internal documents from customer-facing retrieval (e.g., internal emails, sensitive security runbooks).
• Set up filters to prevent:
  • Sharing internal URLs, IPs, or code snippets.
  • Answering certain topic categories at all.
• Maintain auditable logs of:
  • AI prompts and responses.
  • Actions taken based on AI suggestions.
  • Human overrides.

These safeguards protect your brand and customers while still allowing AI to drive meaningful efficiency.

Change Management: Bringing Support Agents and Stakeholders Along

The biggest risk in an AI migration isn’t the technology; it’s people. Agents worry about being replaced, managers fear metric swings, and other teams may be skeptical.

1. Position AI as a copilot that makes agents better

A 2023 MIT/Stanford working paper studied a generative AI assistant deployed to over 5,000 support agents at a large software company. With AI:

• Agents were about 14% more productive (more issues resolved per hour).
• Less-experienced agents improved up to ~35%, narrowing the gap with veterans.
• Customer satisfaction went up, escalations went down, and agent attrition decreased (source).

Share findings like this with your team. The message: AI levels up agents, especially newer ones. It doesn’t eliminate the need for their expertise.

Salesforce’s State of Service report also shows many service professionals view AI and automation as ways to reduce repetitive work and focus on complex cases, helping with burnout (source).

2. Involve frontline agents early

• Invite top agents and skeptics into:
  • Intent definition workshops.
  • Knowledge review sessions.
  • Early testing of AI drafts and flows.
• Ask them:
  • Which conversations are most painful and ripe for automation?
  • Which ones should always stay human?
  • What would a “perfect copilot” look like in their workflow?

This not only improves your design; it builds ownership and reduces resistance.

3. Provide clear training and guardrails

Create practical training for agents covering:

• How the AI assistant works (in plain language).
• Where it’s used (customer-facing vs draft-only).
• When to trust vs override AI suggestions.
• How to flag bad answers or knowledge gaps.

Prosci’s benchmark study found that projects with excellent change management—solid communication, training, and frontline involvement—are 6× more likely to meet or exceed their objectives than those with poor change management (source). Treat agent enablement as a core workstream, not an afterthought.

McKinsey’s research on digital transformation similarly found that around 70% of initiatives fail to achieve their goals, often due to people and process issues rather than the technology itself (source). Avoid that trap by investing in:

• Regular updates and demos of progress.
• Clear escalation channels for concerns.
• Recognition for agents who contribute great knowledge or feedback.

4. Align stakeholders across the business

Bring in:

• Product and engineering (for integrations and roadmap alignment).
• Legal and compliance (for risk and policy decisions).
• Sales and customer success (for messaging to key accounts).
• Marketing (if the assistant surfaces in public properties).

Share:

• The migration plan and phases.
• The scorecard metrics you’ll track.
• Guardrails and escalation policies.

This reduces surprises and builds confidence that you’re taking a measured, responsible approach.

Technical Implementation Checklist for Migrating Off Legacy Bots

With strategy and change management in place, you need a concrete technical plan. Use this as a starting checklist.

1. Data and integrations

• [ ] Export conversation logs from the legacy bot and support channels.
• [ ] Connect your ticketing system (e.g., Zendesk, Intercom, Freshdesk, Salesforce) to the AI platform.
• [ ] Integrate CRM and user store for personalization (plans, segments, VIP flags).
• [ ] Integrate authentication/SSO for logged-in experiences.
• [ ] Establish APIs for key actions (password resets, refunds, order updates).

2. Knowledge ingestion and retrieval

• [ ] Crawl or import your help center and documentation.
• [ ] Import internal knowledge sources (macros, SOPs, policy docs) with appropriate access controls.
• [ ] Set up a vector database or search index with:
  • Chunked content (small, meaningful sections).
  • Metadata (product, region, audience, version).
• [ ] Configure retrieval rules:
  • Which sources are customer-facing vs internal-only.
  • Per-intent or per-segment filters if needed.

3. AI configuration

• [ ] Define system prompts for:
  • Customer-facing assistant tone and boundaries.
  • Agent-assist behaviors (concise, action-focused, etc.).
• [ ] Configure RAG: connect model to retrieval layer.
• [ ] Implement safety filters (banned topics, sensitive terms).
• [ ] Set per-intent policies: autopilot, draft-only, or no AI.

4. Conversation and UI flows

• [ ] Design new chat widget behavior (entry messages, quick replies, escalation button).
• [ ] Implement forms for structured data collection where needed.
• [ ] Build escalation flows:
  • Criteria for handoff.
  • Transfer of context and summaries.
• [ ] Localize UI elements and responses for key languages.

5. Observability and tooling

• [ ] Set up dashboards for:
  • Volume, CSAT, FCR, AHT.
  • Containment and escalation rates.
  • Per-intent performance.
• [ ] Implement logging for AI prompts, retrieved sources, and responses.
• [ ] Build admin tools for:
  • Reviewing conversations and feedback.
  • Updating knowledge and intents.

Real-World Migration Timeline: 30-60-90 Day Example Plan

Timelines vary by organization size and complexity, but a 30-60-90 day framework is a useful planning tool.

Days 0–30: Discover, audit, and prototype

• Complete the bot and content audit:
  • Entry points, flows, and intents.
  • Knowledge inventory and quality review.
• Define intent taxonomy and risk tiers (Tier 1–3).
• Choose your AI support platform and set up:
  • Sandbox environment.
  • Initial knowledge ingestion and retrieval.
• Run small internal prototypes:
  • Let a few agents try AI-assisted replies on historical tickets.
• Communicate the plan to stakeholders and frontline teams.

Deliverables:

• Documented intents and outcomes.
• Prioritized pilot intents and surfaces.
• Initial AI assistant prototype in a non-production environment.

Days 31–60: Shadow mode and limited live experiments

• Run shadow mode on real traffic:
  • AI drafts answers in parallel with existing bot or agents.
  • Collect evaluation data on correctness and completeness.
• Refine knowledge and prompts based on shadow findings.
• Start limited live experiments:
  • Autopilot a small set of Tier 1 intents for a narrow segment/channel.
  • Keep robust fallback to agents and clear labeling.
• Begin agent training on working with AI (especially for draft-mode assistance).

Deliverables:

• Shadow mode performance report.
• Go/no-go list of intents for expanded automation.
• First live AI-handled conversations with monitoring.

Days 61–90: Scale, optimize, and institutionalize

• Expand coverage:
  • Add more Tier 1 intents to autopilot.
  • Gradually include additional segments or channels as metrics allow.
• Implement A/B tests:
  • AI assistant vs legacy bot or vs human-only for certain flows.
• Harden operational processes:
  • Regular review/triage of AI feedback.
  • Clear ownership for knowledge and intent updates.
• Finalize governance:
  • Risk and compliance sign-offs.
  • Documentation of runbooks and escalation paths.

Deliverables:

• Stable AI support assistant handling a meaningful share of volume.
• Migration scorecard with before/after comparisons.
• Ongoing optimization plan and owners.

If you operate in highly regulated environments or have complex products, expect this to stretch beyond 90 days—but the phases remain similar.

Post-Launch: Continuous Tuning, Feedback Loops, and A/B Tests

Launch is just the beginning. The best AI support orgs treat their assistants as living systems.

1. Build tight feedback loops

From customers:

• Add a one-click rating after the AI’s answer (helpful / not helpful), plus optional comments.
• Watch for intent patterns in negative feedback (“billing disputes”, “refund policy”).

From agents:

• Let agents thumbs up/down AI drafts, with a quick reason (“incorrect”, “outdated policy”, “tone off”).
• Provide an easy way to:
  • Suggest new intents.
  • Flag missing or wrong knowledge.

Use this feedback to:

• Update or create knowledge articles.
• Refine prompts and policies.
• Adjust intent definitions and routing rules.

2. Use A/B testing to iterate safely

Intercom reported that early adopters of its Fin AI agent were able to fully resolve over 50% of incoming support queries automatically, often with CSAT at or above human-handled conversations (source). Reaching that level requires experimentation, not just a one-off launch.

Similarly, the AI automation platform Ada notes that many customers automate 30–70% of inquiries once knowledge and flows are properly modeled (source).

To approach these benchmarks:

• A/B test:
  • Different prompt styles (more detail vs more concise).
  • Variations in tone and formatting.
  • Different fallback thresholds and escalation rules.
• Compare:
  • CSAT and CES.
  • Containment and escalation rates.
  • Agent edit rates on AI drafts.

Make small, controlled changes and roll forward only what improves both automation and experience metrics.

3. Monitor for drift and emerging issues

Over time:

• Your product changes.
• Policies and pricing evolve.
• Customer behavior shifts.

Monitor:

• Increase in “I don’t know” or fallback responses for specific intents.
• New trending queries that don’t map to existing intents.
• Spikes in negative feedback or escalations after product launches or policy changes.

Schedule regular (e.g., monthly) review sessions with support ops, content owners, and product to close these gaps.

Conclusion

Moving from a legacy button-based chatbot to a modern AI support assistant is no longer a “nice to have.” Customers expect fast, low-effort digital self-service and easy access to humans. Your competitors are already investing in AI, and the productivity gains are real.

But you don’t have to choose between innovation and stability.

By:

• Auditing existing flows and grounding your design in real intents,
• Preparing a strong knowledge foundation,
• Designing transparent experiences with robust fallbacks,
• Running AI in shadow mode and rolling out in stages,
• Defining a balanced migration scorecard,
• Handling edge cases with strict guardrails, and
• Bringing agents and stakeholders along at every step,

you can modernize your support stack without breaking CX or SLAs—and end up with a system that’s more flexible, more efficient, and more loved by both customers and your team.

Start small: pick a single channel, a handful of low-risk intents, and run a tightly monitored pilot. With the right strategy and tools, you can turn AI support from a risky experiment into a durable competitive advantage.
