Zero-downtime database migrations execute schema and data changes without service interruption by using additive strategies, non-breaking renames, and validation steps. This Skill covers migration patterns across Sequelize, TypeORM, and Prisma with built-in rollback procedures to maintain availability during production deployments.

Yes, this Skill handles cross-ORM migrations by automating schema transformations and data movements between Sequelize, TypeORM, and Prisma. It manages the complexity of translating between different ORM syntaxes and data models while maintaining data integrity and rollback capability.

Database migrations include defined rollback procedures that reverse schema and data changes if issues arise during or after deployment. Rollback scripts are automatically generated alongside migrations to ensure you can safely revert to the previous state.

Data transformation hooks within migrations allow you to define custom logic that safely moves and restructures data across columns and tables. The Skill provides reversible transformation patterns compatible with production deployment cycles.

No. This Skill works with Sequelize, TypeORM, or Prisma individually. Dependencies are based on your chosen ORM; you select the migration tool that matches your existing database layer without requiring all three.

Non-breaking column renames use a multi-step strategy: add the new column, migrate data, update application code, then drop the old column in a later release. This Skill automates these steps with validation to ensure no downtime or data loss.
