Database Migration

About

The Database Migration skill empowers developers to manage schema and data transitions seamlessly across major ORMs like Sequelize, TypeORM, and Prisma. It provides structured guidance for high-stakes database operations, including safe schema transformations, multi-step column renaming, and complex data backfilling. By emphasizing zero-downtime deployment strategies and robust rollback procedures—such as transaction-based and checkpoint-based methods—this skill ensures that database updates are performed with minimal risk to production environments and data integrity.
