Ken, Joe,
Not exactly what I wanted to hear but pretty much what I expected.
I've got about 100 jobs; more of a pain than all that difficult to recreate.
I'm probably being paranoid about wanting the clean install but if I did the upgrade, it would be the fifth Backup Exec upgrade, the third server move and the second tape library change. My experience tells me that it is time for a fresh start..
Thanks for the replies.
