Execute a zero-downtime Convex schema migration by applying a widen-narrow workflow with the @convex-dev/migrations component, allowing the system to handle both old and new data formats during deployment without downtime.

The best way to backfill existing documents during a Convex schema migration is to use batch processing through the @convex-dev/migrations component, ensuring data integrity while you add, remove, or change field types.

Yes, you can dry-run a Convex data migration using the @convex-dev/migrations component to validate changes safely and check migration status before executing batch processing on your live deployment.

You need the widen-narrow pattern for online Convex migrations when accommodating breaking changes like adding or removing fields, changing types, or splitting tables while preserving data integrity during zero-downtime deployments.

Yes, the @convex-dev/migrations component supports batch processing for schema backfills, providing guidance for dry-run validation, status checks, and reversible data modifications during online migrations.
