Please read TECH156810 before NBU 7.1 upgrade
If you are planning to upgrade your NetBackup servers to 7.1, please read TECH156810 before you do:
Symantec hasn't posted this on the Late Breaking News link for NBU 7.1 yet, so I'm hoping this might save some folks a little headache and potentially a LOT of time upgrading.
In a nutshell, there is a problem with the 7.1 installation that will convert your existing NBU policies to a new 7.1 format. However, it needs to communicate with the NBEMM process on your server, but that process will have been shut down prior to this point in the install. The install script will still try to convert each Windows policy one at a time and will time out after about 5 minutes or so; this would have taken an additional 6 hours in our enviornment of about 58 Windows policies.
The Tech Note documents a process to skip this step and then run it after the upgrade script completes. FYI, it's a little involved.
