I know I've seen this but can't find a reference ... AH found http://tracker.firebirdsql.org/browse/CORE-3121 now and http://firebird.1100200.n4.nabble.com/Error-Restoring-v2-1-Database-to-v2-5-td2994314.html
I don't remember backing up this particular site BACK to 2.1 but it is always possible. There are a few things which broke moving to 2.5 and the reason for moving up now is to test prior to updating on site. So is all that is needed to delete RDB$ADMIN from the 2.1 version prior to backing up? The site is live again now so I can't do anything until tonight now. -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk
