I haven't been following this conversation so I might not be helping
here. But maybe ...

1. Take a backup of all your models just in case.

2. Adjust all your models so they exactly match the tables as they
currently stand

3. Delete all your South migration data in app sub-directories

4. Drop all the South tables

5. Remove South from INSTALLED_APPS

6. Run manage.py syncdb to prove there are no errors in what is left. It
is possible that will clean South out of your content_type but I'm not
sure about that. If so it doesn't matter.

7. At this point you have a system ready for South to be installed so go
ahead and do that according to the South docs

8. Follow the South docs to create the intial migration

9. Adjust your models one change at a time and migrate each one
successfully before tackling the next one. Stop when your models match
the backup from step 1.

Good luck

Mike
