Netbackup migration and upgrade from 6.5.6 32bit to 184.108.40.206 64bit
I have 2 master servers out of which 1 is having 1 media server. All are in Windows 2003 R2 32 bit OS and running NB version 6.5.6
We are planning to upgrade the master and media servers to 7.x version but as 32 bit is not supportable in future versions so management has approved for 3 new servers having Windows 2008 64 bit OS.
Now how can I upgrade these servers to 220.127.116.11 as these environments having VM backups and as per one technote 7.5 is still having some issues regarding VStorage backups in its latest version. So, we are planning for upgrade it to till 18.104.22.168 which is relatively stable version.
I understand that I need to install NB in these new servers till 6.5.6 and migrate it first before going for upgrade to 22.214.171.124.
Can someone please help me out with the steps I need to follow while doing this migrate->upgrade and is there any concern/suggestion regarding this upgrade ?
