Introduction

Database migrations are essential for managing schema changes across different environments. This article covers best practices for safe and reliable migrations.

Key Principles

Version Control

Always keep your migration scripts in version control alongside your application code.

Reversibility

Write migrations that can be rolled back. Include both up and down migration scripts.

Testing

Test migrations thoroughly in development and staging environments before production deployment.

Common Pitfalls

• Running migrations without backups
• Making breaking changes without a rollback plan
• Ignoring migration dependencies
• Not handling data transformations carefully

Tools and Frameworks
