Does Django consists of a migration concept without south app?
If not why didn\'t they include it in Django 1.4? (Since, it\'s a must have).
South is not the only migration app that works with Django. See http://djangopackages.com/grids/g/database-migration/ for some current options. Simon Willison also co-created Dmigrations but it's old and hasn't had a commit for a few years.
South is generally accepted to be the best at the moment, though I've not tried NashVegas (partly because South is so good, I've not needed to)
