How to migrate back from initial migration in Django 1.7?

You can do the same with Django 1.7+ also:

python manage.py migrate <app> zero

This clears <app> from migration history and drops all tables of <app>

See django docs for more info.

you can also use the version number:

python manage.py migrate <app> 0002
