CX & Contact Center AI
How do you migrate an IVR to conversational AI?
Migrate in stages rather than replacing the IVR wholesale. Baseline call reasons and containment, fix the prerequisites — authentication, back-end APIs, routing data — then cut over the highest-volume intents behind a fallback to the existing flow, and tune weekly on real transcripts. Skipping the prerequisite work is what costs containment in the first six months.

Key takeaways
- Call-reason baseline firstTranscript analysis of actual call reasons replaces the menu tree assumptions that shaped the legacy IVR.
- Cut over behind a fallbackEach migrated intent keeps a route back to the legacy flow until its containment and escalation quality hold for several weeks.
- Weekly tuning is the migrationThe build gets you to live traffic; the tuning loop on real transcripts is what actually reaches the target containment.

- 40–60%
- Skipping the migration prerequisites costs 40% to 60% of expected containment in the first six months of an IVR-to-conversational-AI cutover.Source: CCaaS Modernization: IVR to Conversational AI →
- 85%+
- Simple transactional intents should target 85%+ containment; complex informational intents 40% to 55%. Anything involving discretion or empathy should escalate immediately.Source: CCaaS Modernization: IVR to Conversational AI →
- 5–10%
- Agentic rollouts that hold their SLAs canary at 5% to 10% of traffic with instant fallback before ramping 25 / 50 / 100 behind SLO gates.Source: CCaaS Modernization: IVR to Conversational AI →
