please help, what are preupgrade steps, what are risk involve
i want to upgrade the OS as well from 2008 to 2012, what are best practice i need to follow to done this operation.
Since you are on NetBackup 7.1 version, you would need to perform an NBCC check on the master server to start with.
If any inconsistencies are reported, then a case with support would be required to fix them. Ofcourse without support exception this would not be possible.
If no inconsistensies are reported take a FULL catalog backup and perform the upgrade. If your catalog size is not too large you can directly upgrade to NetBackup 8.0. Once upgraded wait for the catalog migration to complete successfully. Then take another FULL catalog backup and migrate to the new OS i.e. Windows 2012. If you are moving to a new hardware, you would need to install NBU 8.0 on the new server keeping hostname and install path same and then perform a catalog recovery.
If your catalog size is large, I would recommend upgrading to either 7.6.1 or 7.7.3 version from the current NetBackup version. Once successful wait for the catalog migration to complete, then take another FULL catalog backup followed by upgrading to 8.0 or higher.
Any particular reason why you are planning for 8.0 and not the latest or n-1 version of NetBackup.?
Start with Veritas SORT:
Technically it's possible to upgrade straight to 8.0.
