Data Protector is in a hpux 11.31 MC/SG cluster. So I have to upgrade each of the nodes, then import the virtual server, correct ? The package must be down ?
Yes
=================
What version of DP 8 should I install ?
I highly recommend against installing DP 8.1, and recomend 8.0 only if you immediately install patch bundle 8.01
==================
What are the issues when upgrading DP 7 to DP 8 ?
Therer were lots of issues with the IDB found during the upgrade. These have mostly been fixed with the 8.01 patch, but, I don't think that they are totally fixed yet
