I did a 3.6 to 4.1 like this. I moved all of my VMs to a new storage doma= in (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 tha= n expected mac address changes, but I think you can manually override this = in the engine somewhere If you are worried, do it with one VM. Create a new storage domain that b= oth clusters can "see", move one VM to the domain on 3.6, detach, and import = to 3.1. Bring the VM up
If it is Linux VM's older than systemd and using sysvinit, you will hit i= ssues where your MAC address will change and udev will move it to eth# wherever= # is the next available NIC in your VM host

- I have a productive ovirt cluster based on 3.5 series. This using a s= hared nfs storage. Is it possible to migrate VMs from 3.5 to 4.1 with detach shar= ed storage from the old cluster and attach it to the new cluster? - If yes what will happend with the VM properies? For example mac addre= sses, limits, etc. Those will be migrated or not?
Thanks in advance, Regard
Tibor
