I have changed the master server in pre 6.0 version and it may still be true. 
In pre 6.0 version, I did cold catalog backup on master server (pre 6.0 style) 
and used on a new master used bprecover command with -dhost option, here you 
could specify the new master srver name. I did work very well.
