How does it handle zero-downtime migrations?

It utilizes multi-phase strategies, such as the 'Expand and Contract' pattern, to ensure database changes remain backward compatible with the application during deployment.

Is it suitable for cross-database migrations?

Yes, it includes examples for handling dialect-specific differences between major databases like PostgreSQL and MySQL.

Does it provide rollback support?

Absolutely. Every migration pattern emphasizes the 'up' and 'down' approach, including transaction-based safeguards to prevent partial migration failures.

Can I use this for complex data transformations?

Yes, it includes specialized logic for data transformations, including splitting columns, migrating records between tables, and safe data backfilling.

Which ORMs does this skill support?

It provides standardized patterns and best practices for Sequelize, TypeORM, and Prisma, as well as general SQL-based migration strategies.
