Goodbye Press 1: Migrating from Legacy IVR to Conversational AI

"Press 1 for sales. Press 2 for support. Press 3 to speak with an operator. Press 4 to hear these options again." Your customers hate it. Your data shows it. But replacing a system that handles millions of calls feels terrifying. This guide makes it manageable.

I've led 75+ IVR migrations. Zero have resulted in major outages. Here's the playbook.

Phase 1: Discovery & Planning (Weeks 1-4)

Document Your Current State

• Map every IVR menu path and option
• Identify call volumes for each path
• Document integrations (CRM, databases, APIs)
• List all prompts and recordings
• Note any compliance requirements

Analyze Call Patterns

Pull 90 days of IVR data. Answer these questions:

• Which menu options get 80% of traffic?
• Where do customers abandon or zero-out?
• What do customers say when they reach an agent?
• Which paths could be fully automated with AI?

Define Success Criteria

Be specific: "Increase containment from 22% to 50%" or "Reduce average handle time by 30 seconds" or "Eliminate menu navigation entirely."

Phase 2: Parallel Build (Weeks 5-10)

Build AI Alongside IVR

Don't turn off your IVR. Build the conversational AI system in parallel while IVR continues handling calls.

Start with Highest-Volume, Lowest-Risk

Don't try to replace everything at once. Pick your top 3 call types that are:

• High volume (meaningful sample size)
• Well-understood (clear resolution paths)
• Low risk (not complex compliance situations)

Phase 3: Gradual Rollout (Weeks 11-20)

The Ramp Schedule

Rollback Criteria

Define in advance when you'll roll back:

• Containment rate drops below X%
• Customer satisfaction drops below Y
• Error rate exceeds Z%
• Any compliance violation detected

Common Migration Pitfalls

Pitfall 1: Trying to Replicate IVR Logic

Don't build "conversational IVR." Conversational AI should handle intent directly, not force users through menu structures.

Pitfall 2: Underestimating Edge Cases

Your IVR has years of edge case handling built in. Document these carefully they're easy to forget and painful to rediscover.

Pitfall 3: Ignoring Agent Training

Agents need to know how AI handles calls. What context will they receive? How do handoffs work? Train before launch.

Pitfall 4: Big Bang Deployments

Never flip 100% of traffic overnight. Even if testing looks perfect, production traffic always surprises you.
