Netbackup Upgrade from Netbackup 7.5.0.4 to 7.6.0.2

Hi All,

I have a windows server 2003 as master server, version of NBU is 7.5.0.4.I need to upgrade the Netbackup version to 7.6.0.2 on a new server, windows server 2012. I have a problem about this, Netbackup 7.6.0.2 does not support windows 2003(64bit) and Netbackup 7.5.0.4 does not support Windows 2012. The plan is to have a staging server, windows 2008. Can someone tell me all the necessary procedures/ steps?
