<div dir="ltr">I did a 3.6 to 4.1 like this. I moved all of my VMs to a new storage domain (the other was hyperconverged gluster) and then took a full outage, shut down all of my VMs, detached from 3.6, and imported on 4.1. I had no issues other than expected mac address changes, but I think you can manually override this in the engine somewhere<div><br></div><div>If you are worried, do it with one VM. Create a new storage domain that both clusters can "see", move one VM to the domain on 3.6, detach, and import to 3.1.
