I'm using south to migrate schemes to production. Also I'm using the django-sitetree module to show the menu in my site.
There is no problem with schema migration by using commands:
./manage.py schemamigration myApp --freeze sitetree --auto
./manage.py migrate myApp
However when I'm trying to migrate the sitetree data by command:
./manage.py datamigration myApp "new_version" --freeze sitetree
it doesn't generate any of created sitetree elements.
