Zero-downtime Convex schema migrations are coordinated by adding optional fields, running batched backfills, and then updating the schema while keeping code paths compatible. This ensures no data loss or service interruption during live deployments.

Backfilling existing data in Convex is best handled using batched execution patterns. A reusable migration runner tracks progress across batches, allowing you to safely populate new optional fields for existing records without downtime.

Yes, you can remove deprecated fields from a Convex schema safely by keeping code paths compatible during the transition. The migration patterns ensure your application continues operating without errors while deprecated fields are phased out.

Index migration in Convex works through safe, batched execution managed by a reusable migration runner. This approach handles index changes and multi-step field renames while tracking progress to ensure zero-downtime schema evolution.

No, you do not need to take your application offline to update a Convex database schema. By coordinating field additions, backfills, and removals with a migration runner, you can evolve schemas safely in live deployments without downtime.
