Yeah I did, and now I've read the upgrade notes, I see what a silly
question that was :) That is one tough "upgrade" process, basically
recreate the cluster ...

Think I'll go for the 2nd way - backup everything, reinstall from scratch,
restore backups. Good opportunity to redesign my storage.

Gotta be a difficult upgrade for large enterprise clusters, bad enough for
my little 3 node setup.
