Comment (by nimasmi):

 FWIW django-extensions has fixed it internally (https://github.com/django-
 extensions/django-
 extensions/commit/dbabd69e48e682916e0ffdc7a3567f8fe148ddf3,
 https://github.com/django-extensions/django-
 extensions/blob/master/CHANGELOG.md#159), but I acknowledge that Django
 should expect other third-party apps not to toe the line.

Comment (by ryuusenshi):

I'm not even sure if this should really be fixed on django's side, but
I've created another

[https://code.djangoproject.com/attachment/ticket/25618/django_style_migrations_fix.diff
patch], just in case.

This patch would make it so that in the case such as `django-extensions`
where south `migrations` module was just left hanging around, against
instructions to be moved, Django would just ignore those migrations.

I will create a pull request later, and let the core developers decide
whether this should be addressed or not.

Re: [Django] #25618: Django migration system breaks with unhelpful error message if south migrations accidentally retained

Comment (by ryuusenshi):

The problem is actually in the fact that `django-extensions` is using the
`migrations` module to store south migrations and still claims to support
Django 1.4 and later. However, since 1.7 the `migrations` module was
reserved for Django migrations, and even the
[http://south.readthedocs.org/en/latest/releasenotes/1.0.html last
official release of South] instructs developers to move south migrations
to `south_migrations` module.

So, in conclusion, `django-extensions` never really fully supported Django
1.7+.

Comment:

 The "fix" breaks `django_extensions` and possibly a lot of other packages
 that have support for pre django 1.7 versions.
