Thanks, but that is an answer to a different question I didn't ask.

It does, implicitly, seem to indicate that there probably are artifacts on 
hosts that need to be preserved, and hopefully I can find specifics in that 
script .

[ovirt-users] Upgrade via reinstall?

[Jamie Lawrence]

Hello,

I currently have an Ovirt 4.1.8 installation with a hosted engine using Gluster 
for storage, with the DBs hosted on a dedicated PG cluster.

For reasons[1], it seems possibly simpler for me to upgrade our installation by 
reinstalling rather than upgrading. In this case, I can happily bring down the 
running VMs/otherwise do things that one normally can't.

Is there any technical reason I can't/shouldn't rebuild from bare-metal, 
including creating a fresh hosted engine, without losing anything? I suppose a 
different way of asking this is, is there anything on the engine/host 
filesystems that I should preserve/restore for this to work? 

Thanks,

-j

[1] If this isn't an option, I'll go in to them in order to figure out a plan 
B; just avoiding a lot of backstory that isn't needed for the question.
