Subject: Re: HMC V9 vs V10, Was: Bringing IBM i up to the "latest" OS patches

In my case, there isn't much customization at all. I am still relatively new to the HMC so I use it sparingly. So, if I understand you correctly, just creating a new VMWare instance using the provided vHMC image would be relatively easy? I would just have to use the correct network settings so it can find my existing partitions (2 - 1 IBMi and 1 Linux) ?

Right now my biggest question is the install media for an upgrade vs update. I can find the install image (iso) to update the current vHMC to the latest v9r1 fix level. But I can't seem to find an iso that is an "upgrade" from v9r1 to v9r2. I can find VMWare images for v9r2 and also can find an "update" image to take an existing v9r2 to the latest fix levels. But I haven't found "upgrade" images for v9r1 to v9r2.

Maybe I'll try the VMWare image and see if I can get it connected and working.....

IMHO, if the target HMC version supports your hardware and firmware
(v10 supports P10, P9 and P8) I would see no problem in moving to
that. And unless you have a lot of customization on the HMC (users,
groups, permissions, that kind of stuff) you could just spin up new
HMCs and move the machines to them.
