How does this skill help with zero-downtime migrations?

It implements 'expand-contract' patterns, adding new columns and synchronizing data while keeping the old schema active, ensuring the application remains functional throughout the transition.

Can this skill help with failed migrations?

Yes, it includes advanced rollback strategies using transaction-based migrations and checkpoint-based restores to ensure data integrity if a migration fails.

Is it suitable for cross-database migrations?

Absolutely. It handles dialect-specific differences, such as moving from PostgreSQL to MySQL, by adjusting data types like JSON vs JSONB automatically.

Which ORMs are supported by this Claude Code skill?

The skill provides specific guidance, code templates, and best practices for Sequelize, TypeORM, and Prisma, as well as raw SQL migration strategies.
