Migrating from Vapi to VocazAI: the one-weekend guide
You deployed on Vapi and the per-minute bill is starting to sting. Here's the migration to VocazAI in one weekend — steps, watch-points, what carries over and what doesn't.
Vapi is an excellent platform to iterate on. But after a few months in production at real volume, plenty of operators notice the pay-per-minute model adds up — especially trilingual. Here's how to migrate to VocazAI without breaking prod, in one weekend.
Before migrating — when it's worth it#
- You're past 300 minutes/month (pay-per-minute starts to diverge from there).
- You want clean trilingual without juggling 3 separate configs.
- You need a signed GDPR DPA out of the box.
- You want human support that answers in under 4 hours.
Friday night — export and inventory#
Export from Vapi: current system prompt, list of connected tools (calendar, CRM, webhooks), voice in use, phone number and telco. Document current KPIs (latency, duration, conversion). You'll need those baselines to compare after.
Saturday — VocazAI configuration#
We take your system prompt almost as-is — tool-calling syntax is compatible. We plug your calendar and CRM (standard connectors take 30 minutes). We pick the voice per language. You call the VocazAI agent from your own phone and test 10-15 scenarios.
Sunday — progressive number switch#
You ask your telco to forward your number to VocazAI for 4 hours Sunday evening (calm window). If everything works, extend overnight, then full from Monday morning. Rollback is one minute if needed.
What carries over, what doesn't#
Carries over: prompt, transfer logic, tool scenarios. Doesn't: historical transcripts (Vapi doesn't export them in a standard format), Vapi custom-trained voices (re-config on VocazAI side), legacy analytics (fresh start).
Concrete cost#
500 trilingual minutes/month on Vapi: ~$2,100/mo depending on LLM and voice. On VocazAI Growth: $1,490/mo all-in. Annual saving ~$7,300. First month free to benchmark in parallel before full switch.
