In place upgrade. Seems like the accepted path is upgrade BM from 3.7sp3 to 3.8sp3, and then upgrade the OS to 6.5sp3.

I was thinking of unloading BM and upgrading the server to 6.5sp3 first, upgrade TCPIP and NICI, and then installing BM 3.8sp3. Would this work, and has anyone tried it successfully? Would the BM install still pick up all of the previous settings? Am I being an idiot and should just stick to the recommendation of upgrading BM first?
