How to switch from Estuary.
Moving off Estuary means re-creating connectors and sync schedules, mapping schemas and history tables, re-running backfills, rebuilding transformations and alerts, and running old and new pipelines in parallel until row counts match. Plan for extra usage charges during backfills. Connect your three most important sources in each shortlisted tool, run a full backfill and a week of incremental syncs, and compare reliability, latency and the projected monthly bill.
- Export a sample of your Estuary data and test an import into the new product.
- List the automations, integrations and permissions you would need to rebuild.
- Compare total cost for your real seat count, including add-ons and onboarding fees.
- Pilot with one team before a full cut-over.
- Check contract terms, renewal dates and notice periods with Estuary.
