Emigrate

The modern, modular and flexible migration tool for any database

It's effectively a successor of klei-migrate and Immigration.

Features

• Database agnostic
  • Emigrate can migrate any database
• Works at any scale
  • Supports any database as storage so multiple instances can share the same migration history
  • Uses smart locking to ensure only one instance migrates a certain migration at a time
  • Thanks to the smart locking it's safe to run migrations in parallel
• Can be run inside containers
  • It's common for Docker or Kubernetes to kill containers with health checks if migrations takes too long to run
  • Emigrate makes sure the migration history does not get stuck in a locked state if that's the case
• Supports any file type for your migration files
  • You can easily write migrations in JavaScript, TypeScript or plain SQL (or any other language)
  • You can customize the template for your migration files to fit your needs (or use a plugin to do it for you)
• Easy to debug
  • Emigrate will store any errors that occur during migration in the migration history so you can easily debug them
