i meet same problem when move 1.6.* 1.10.finally found problem cause database_routers
the old version write
class onlinerouter(object): # ... def allow_migrate(self, db, model): if db == 'myonline': return model._meta.app_label == 'online' elif model._meta.app_label == 'online': return false return none it work rewrite this
class onlinerouter(object): # ... def allow_migrate(self, db, app_label, model_name=none, **hints): if db == 'my_online': return app_label == 'online' elif app_label == 'online': return false return none more detail see https://docs.djangoproject.com/en/1.10/topics/db/multi-db/#an-example
