To perform zero-downtime schema migrations in Convex, use phased rollout strategies that maintain backward compatibility. This approach allows adding fields, backfilling data, and removing deprecated fields without causing downtime or data loss.

The best way to backfill data in Convex is using safe migration patterns that support backward-compatible transitions. This allows you to add new fields like profile settings to existing user tables while ensuring current records remain valid during the rollout.

Yes, you can use phased rollouts for index migrations in Convex. The migration patterns specify step-by-step strategies to safely evolve indexes and schemas across environments with minimal disruption to ongoing operations.

To safely remove deprecated fields from a Convex database, follow a phased migration strategy that ensures backward compatibility first. Remove the fields only after all code references are updated and existing data is transitioned.

Zero-downtime migrations in Convex require careful governance and tracking to avoid limitations like data loss. You must support multiple schema versions simultaneously during rollout, which adds complexity to the transition process.
