To convert to django-south operations, easiest is if you are willing to drop your old database (e.g. delete evennia.db if you use default sqlite3). Then do: "game/manage.py syncdb" followed by "game/manage.py migrate". That should do it. If you ever deletes your database, just rerun those two commands.
If you want to convert an existing database, do
game/manage.py convert_to_south comms
game/manage.py convert_to_south config
game/manage.py convert_to_south help
game/manage.py convert_to_south objects
game/manage.py convert_to_south players
game/manage.py convert_to_south scripts
In the future, you will then be able to do ./manage.py migrate when we tell you the schema has changed.
