Hi, I am palnning to upgrade the netbackup version from 18.104.22.168 to 6.5.6. can you share the steps ands what are the things am I need t download.
You'll probably find all the instructions you need in the actual Tech Note that contains each download.
As far as what you need to download, that depends on what you've got! O/S, agents & options etc etc.

"Have you still got the box it came in?"
Isn't it best to go for V7
e.g. it could be easier to push through a change request for a 'patch' as opposed to an 'upgrade', O/S incompatibilty etc
