Which ORMs does this database migration skill support?

The skill provides specific implementation patterns and best practices for popular JavaScript/TypeScript ORMs including Sequelize, TypeORM, and Prisma.

What safety measures are implemented for risky migrations?

The skill emphasizes transaction-based migrations to ensure atomicity, checkpoint-based rollbacks with temporary backup tables, and idempotent script design.

How does the skill handle zero-downtime migrations?

It utilizes a multi-phase approach: creating backward-compatible changes, deploying dual-writing code, backfilling data, and finally removing legacy structures.

Can I use this for migrating between different database engines?

Yes, the skill includes strategies for handling dialect differences, such as converting between PostgreSQL JSONB and MySQL JSON types during migration.
