Perhaps I'm missing something, but essentially you are just replacing
the master server and adding another library, right? This should be no
different that any other hardware+OS change, and very similar to a DR.
So, recover to the existing state on the upgraded/replaced platform,
then optionally upgrade NetBackup to the desired version.
- Catalog backup(s)
- Replace the old box or upgrade Solaris on it
- Hardware connections as appropriate
- Install the same rev of NetBackup
- bprecover
- Rediscover devices
- Test
- [catalog backup/upgrade NetBackup/test as desired]
- Production and duplication of retiring drives and media.
