When I attempted a migration, I got errors about importing South in djcelery! What??! Turns out the version that edx-platform uses has some remaining migrations that are pre-Django-1.7? I upgraded djcelery to the most recent version and tried migration again. Got a message about a table already existing. When I compared the existing schema and the new single 0001_initial.py migration in djcelery, the schema did not match. So some tricky database figuring-out will be required to proceed. The next step:
- Look at https://github.com/celery/django-celery/commits/master/djcelery/migrations
- Figure out if the new migration 0001_initial.py fully represents the state of the DB in the four older migration files 0001-0004.
