Manual upgrade required

[snopoke]

As of cc2bd1f the channels Django app in OCS has been renamed to bot_channels.

This change requires manual steps for deployment since it breaks the Django migrations.

Migration Steps

1. Stop all services
2. Run the following SQL on the database:

UPDATE django_migrations SET app='bot_channels' WHERE app='channels';
DELETE FROM auth_group_permissions where permission_id in (
    SELECT id FROM auth_permission where content_type_id in (SELECT id from django_content_type where app_label='bot_channels')
);
DELETE FROM auth_permission where content_type_id in (SELECT id from django_content_type where app_label='bot_channels');
DELETE FROM django_content_type where app_label='bot_channels';
UPDATE django_content_type SET app_label='bot_channels' WHERE app_label='channels';

3. Deploy any version of OCS after cc2bd1f

Error Message

If you attempt to deploy later version of OCS without the database changes you will see the following error:

django.db.migrations.exceptions.InconsistentMigrationHistory: Migration experiments.0035_experimentsession_experiment_channel_and_more is applied before its dependency bot_channels.0007_alter_experimentchannel_platform on database 'default'.
