Zero-downtime migrations in Convex are achieved through incremental schema updates and data transformation mutations. By applying changes in safe steps, such as adding optional fields and backfilling data first, you ensure data integrity without interrupting application service.

The best way to backfill data during Convex schema evolution is to use data transformation mutations. These mutations safely populate newly added optional fields with default values or computed data across existing documents before finalizing the schema change.

Yes, you can remove or rename fields without breaking your application by implementing safe schema evolution patterns. This involves incrementally updating your schema and transitioning data so deprecated fields are safely removed without causing downtime or data loss.

You need to use data transformation mutations when adding new fields that require existing documents to be updated. They are essential for backfilling default values and ensuring data consistency before you make a newly added schema field strictly required.

Yes, this approach supports zero-downtime migration patterns by applying schema changes through safe, incremental updates. It guides you through making fields optional, backfilling data, and enforcing constraints without interrupting active service.
