Our tables were shared between users -- if this insight helps, and may have been the cause for the failure during the automatic migration process.

The admin user had no access to the tables, as they were created by and shared between standard users.

But this shouldn't have stopped Tables from being to update its MySQL database entries and tables from the backend.
