NetBackup upgrade 7.6.1.2

If both your servers are master servers, it shouldn't matter what order you upgrade them.

The upgrade order is OpsCenter first, then Master Server, then Media Server, the Clients.

When upgrading to 7.6.1.2, you have to upgrade to 7.6.1 first and then apply the patch.

The appliance will let you upgrade straight to 2.6.1.2.

The appliance EEB upgrades the version of NetBackup running on it. If one of your appliances is a master server then it will automatically upgrade to 7.6.1.2 when the appliance code is upgraded to 2.6.1.2. Veritas a while ago normalized the appliance code version with the NBU code version. So if an appliance is running code 2.6.0.1 then the NBU code is 7.6.0.1
