Migrate from djcelery to django_celery_results

Hello,

Is there a documentation about migrating from djcelery to django_celery_results?

It seems there were 6 tables:

 public | djcelery_crontabschedule   | table | 
 public | djcelery_intervalschedule  | table | 
 public | djcelery_periodictask      | table | 
 public | djcelery_periodictasks     | table | 
 public | djcelery_taskstate         | table | 
 public | djcelery_workerstate       | table | 

And now only one:

public | django_celery_results_taskresult | table |

When I rename celery to celery4 and kombu to kombu2 both libraries can be imported at the same time. manage.py sqlmigrate … now helps a little bit to get some SQL commands.

Workaround:

su - postgres -c "psql -d '$POSTGRES_DB' -c \"delete from django_migrations where app='import_api';\""
python3 migrate.py django_celery_results
su - postgres -c "psql -d '$POSTGRES_DB' -c 'ALTER TABLE "foo_bar" DROP CONSTRAINT "foo_barj_result_id_7383b884_fk_celery_taskmeta_id";'"
su - postgres -c "psql -d '$POSTGRES_DB' -c 'ALTER TABLE "foo_bar" ADD CONSTRAINT "foo_bar_result_id_7383b884_fk_django_celery_results_taskresult_id" FOREIGN KEY ("result_id") REFERENCES "django_celery_results_taskresult" ("id") DEFERRABLE INITIALLY DEFERRED;'"
python3 migrate.py --fake-initial foo
