I tried to register one of the existing servers and the error message is This database instance is already registered in this Repository
So at one level, the instance is registered, but at the level where I need to unregister it, it is not registered/not on the list of instances that I can unregister.
This is getting pretty complicated if that means I need to delete a bunch of tables and records in the repository to be able to register the instance again just so I can test if this workaround will work. So I am not going to pursue this angle any more unless Solarwinds techs are sure it will work and can tell me exactly which tables and records to delete.
