Cause
Confluence hit a reference to non-existent user in the os_user_group table, hence it was not able to complete the user migration. The root cause for what has corrupted the table is unknown.
Resolution
Identify the rogue rows that prevented your users from being migrated by running the following query:
1 2select os_user_group.* from os_user_group left join os_user on os_user_group.user_id = os_user.id where os_user.id is null;Delete the rogue user id from your database:
1 2delete from os_user_group where user_id = <user id returned from the query above>;
