When should I use South instead of yoyo-migrations?

Historical Django schema migrations for codebases running Django 1.6 or earlier. Maintaining very legacy Django projects that have not been upgraded in over a decade. Understanding Django migration history — South directly inspired the built-in migrations system

When should I use yoyo-migrations instead of South?

Simple SQL-based database migrations without any ORM dependency. Teams who prefer writing raw SQL migration files over Python DSL or framework-specific tools. Lightweight migration management for microservices or small projects with simple schemas

What are the main weaknesses of South?

Completely obsolete — Django's built-in migrations superseded South in Django 1.7 (2014). Not compatible with Django 2.x or any later version. No active maintenance or security updates; should be removed from any active codebase

What are the main weaknesses of yoyo-migrations?

Limited adoption and community compared to Alembic or Flyway. No ORM integration — schema definitions and migration files must be kept in sync manually. Fewer features than Alembic: no branching support and limited rollback capabilities

How Python Data Engineers Use These Tools

South

Engineers maintaining legacy Django projects running Django 1.6 or earlier use South to manage schema evolution. New projects should use Django's built-in migrations instead. For teams upgrading legacy codebases, South migrations can be converted to Django native migrations using the `manage.py migrate --run-syncdb` workflow.

yoyo-migrations

Python data engineers use yoyo-migrations for managing database schema changes in projects where plain SQL migrations are preferred over ORM-based tools like Alembic or Django migrations. It is used to version-control schema changes for analytics databases, pipeline metadata stores, and data warehouse tables, keeping DDL changes in source control and ensuring consistent schema state across development, staging, and production environments.
