To execute safe Convex schema migrations without downtime, use an online migration workflow that processes data in batches. This approach ensures your application remains fully operational while records are adapted, backfilled, or transformed in the background.

The best way to backfill data when adding new fields in Convex is to define a migration using the migrations component. This allows you to safely populate new fields and transform existing documents without breaking your current application logic.

Yes, you can test a data migration before applying it to production by performing a dry-run. The Convex migrations component supports dry-runs and provides status monitoring to help you verify changes safely prior to full deployment.

To handle changing field types or splitting and merging tables in Convex, apply safe deployment patterns like widening then narrowing schemas. Use the migrations component to orchestrate these complex structural transformations incrementally.

Online Convex data migrations require careful schema widening and narrowing patterns to avoid breaking existing documents. Complex operations like changing field types or splitting tables must be executed incrementally in batches using the migrations component.
