NetBackup 8.1 upgrade - time estimate
Hi, I'm getting ready to upgrade in a couple weeks from NBU Ent Server 7.7.3 to 8.1 and I'm trying to find a way to estimate how long the upgrade will take on the master server.
Master is RHEL 6.9, catalog is 1.2TB, do not use MSDP
Current NBU Ent Server 7.7.3, upgrading to 8.1
Is there a calculator or rule of thumb for estimating how long the upgrade will take on the master server? Need to plan my change control outage window.
Thanks,
Dave Rowley
I upgraded NBU 7.7.2 to 8.1 with 1TB catalog, alhough on Windows in December, the total time for the upgrade was about 6 hours but it was a clustered Master with Global Cluster Option, so this includes also time to disconnect replication, isolate second Master from the network and re-establish replication.
You can check the 8.1 upgrade guide https://www.veritas.com/content/support/en_US/doc/125240132-127350446-0/v85160419-127350446 that provides estimates for the process but many of them apply to older version for whose catalogs massive catalog changes are expected during the upgrade. 7.7.3 to 8.1 is not a big jump and I don't recall any long conversions, even for MSDP they are now online operations (with some caveats about backward compatibility)
