Ola everyone
I guess before the inception of the migration plan, stop all backups currently active or schedule them in such a manner that they complete by desired time, as soon as when all the backups successfully complete, take a catalogue backup.
just in case you may need to revert back, taking in consideration the netbackup 6.0 stability, which is not looking very good.
remove the package for netbackup 5.0
install netbackup 6.0 package
similalry upgrade your media servers
on the master do a nbupushdata as well as in the media servers in successions.
I guess thats all that needs to be done.
Please do get in touch with a Veritas personnel for a accurate POA.
Wishing you all the very best with netbackup 6.0 and GodSpeed.
