When should I use Django Migrations instead of South?

Auto-generating migrations from Django model changes with a single manage.py command. Rapid schema iteration in Django web application development with zero boilerplate. Teams wanting fully integrated migration management tied to their ORM with no extra setup

When should I use South instead of Django 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

What are the main weaknesses of Django Migrations?

Coupled to Django — not usable outside a Django project under any circumstances. Large or complex migrations on production tables can be slow and risky without careful planning. Squashing migrations in mature projects with long history is error-prone and time-consuming

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Completely obsolete — Django's built-in migrations superseded South in Django 1.7 (2014).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

How Python Data Engineers Use These Tools

Django Migrations

Python data engineers use Django migrations to manage schema evolution for Django-backed data applications, internal tooling, and operational databases. Migrations provide a version-controlled history of schema changes that can be replayed in any environment. In data engineering contexts, Django's ORM and migration system are used to manage metadata stores, pipeline configuration databases, and lightweight data catalogue applications built with Django.

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.
