Auto-cleanup of inconsistent data statuses during account migration from #27517
If there are several accounts with the same user name before the migration of #27517, the migration will fail. A manual cleanup of such inconsistent data statuses is extremely difficult. Technical consistency should therefore be established automatically in such cases:
- If there are users with the same login who (historically speaking) were active at the same time, then the username of the older user is supplemented with a suffix to create uniqueness.
- If there are no such duplicate users in the current database, then this clean-up does not change the access to the system, only user names in the past change.
