I made new cluster with Epyc CPU Type and cluster already in 4.3 level. Starting engine in new cluster complained something about not finding vm with that uuid but it still started engine fine. When all nodes were in new cluster I still couldn't upgrade old cluster because engine was complaining that couple of VM's couldn't be upgraded (something to do with custom level). I moved them to new cluster too. Had to just change networks to management for the move. After that I could upgrade old cluster to Epyc and 4.3 level. Then I just moved VM's and nodes back (same steps but backwards). After that you can remove the extra cluster and raise datacenter to 4.3 level. -Juhani
