Does this skill support rollback procedures?

Yes, it provides patterns for transaction-based migrations and checkpoint-based rollbacks to ensure data integrity even if a migration fails mid-way.

Can I use this for zero-downtime deployments?

Absolutely. It details multi-phase strategies, such as adding columns and backfilling data, to ensure the application remains compatible during the transition.

Does it handle cross-database dialect differences?

Yes, it includes logic for handling specific dialect differences, such as the variation between JSON types in MySQL and JSONB in PostgreSQL.

Which ORMs are covered in this migration skill?

The skill includes specific implementation patterns and CLI commands for Sequelize, TypeORM, and Prisma.
