We currently have 2 Netbackup servers. Each one is a master/media server. The plan is to remove one of them as a master so we can have 1 master server and 2 media servers. One is running NBU 6.0 MP4 and the other is NBU 6.0 MP2, and both are on Windows 2003 servers. Also, we'd like to upgrade both servers to NBU 6.5. Is this possible, or is it a nightmare waiting to happen? What would be the order of operations? Support services haven't been helpful much so I'm reaching out to you folks. Thanks in advance for the help.
