Well, if you want to keep that machine as a media 
server, then you would want to move all of the MASTER 
related dbs to a new MASTER server.

That is everything except /usr/openv/netbackup/db/media.

The media DB is unique to each media server in your NBU 
domain.  This contains information about the tape IT 
owns and has written to.

My steps are a bit more lengthy because it keeps the 
original master in place, demotes it to a media server 
and transitions to a new master server.

Its just a matter of understanding what's required for 
each server function.

Short of me posting my consulting documents, I would 
suggest you refer to the troubleshooting guide for 
additional assistance in understanding the different 
dbs and their functions as it pertains to either master 
or media servers.
