database-migration

Zero-downtime database migration requires phased deployment: run migrations on a replica first, verify data integrity, then switch traffic gradually. This Skill implements rollback procedures, transactional migrations, and backups across Sequelize, TypeORM, and Prisma to keep your service live during schema changes.

Yes. This Skill handles ORM-to-ORM migrations with data transformation and backfill strategies. It preserves data integrity through transactional migrations, down() implementations for rollback, and verification steps before committing changes.

This Skill includes rollback procedures and down() implementations so you can revert to the previous schema state safely. Backups and phased deployment support let you test rollback paths before production runs.

Yes. The Skill supports complex schema transformations paired with data migration strategies, including backfill logic to populate new columns or restructure existing data during the migration window.

Each ORM (Sequelize, TypeORM, Prisma) has different migration syntax, transaction support, and rollback capabilities. This Skill standardizes safe practices—transactional migrations, down() functions, and backup procedures—across all three to eliminate brittleness and risk.
