Best way to add Django migrations to a django project
I have done the migration from 1.6 to 1.7 on an existing project.  It was fairly painless.  
I renamed my old South migrations folders and let the django 1.7 migrations create a new one. (i.e. $mv appname/migrations appname/migrations.south)  That will make it easier to go back to South for any reason and will keep from having a jumbled mess of both in your migrations folders.
I have a Django application initially created for version 1.6 and I've just finished the upgrade for the last version. All the models has managed = False and prior none of them was managed by south and now I want to start using Django migrations for 1.7 version.
Which would be the best and seamless way to do it? I'm afraid that just changing managed = True in all models and run manage.py makemigrations will make a mess in both migrations files and database.
Thanks
EDIT
As was suggested I ran manage.py makemigrations. It created the script 0001_initial with some model definitions but not for all the objects in models package. It creates 11 tables but I have 19 tables. All models has managed = True and I don't have any database router.
