I don't think it's a bug either, since it doesn't occur when MediaPortal is used 'normally'. It might be a feature request, although I doubt the priority would be high (DBMS changes do not occur a lot). Perhaps a document on the Wiki explaining what is required for DBMS migration in a multi-seat environment might be enough.now the question remains.. is it a bug ... dont think so , if you cleanly install everything also clients, it wont happen ?
it only happens if you go from DB to another DB while you have clients already installed.
