Hello.
I'm going to upgrade my PVE cluster to v5.3; thus i wish to LIVE migrate VMs from PVE node(s) v4.3 to newly upgraded node (v5.3), but getting error as below:
I CAN migrate to other v4 node, but can not migrate to nodes upgraded to v5;

I'm going to upgrade my PVE cluster to v5.3; thus i wish to LIVE migrate VMs from PVE node(s) v4.3 to newly upgraded node (v5.3), but getting error as below:

you have to upgrade to the latest 4.4 before being able to live migrate to v5.x like it is written in the upgrade guide: https://pve.proxmox.com/wiki/Upgrade_from_4.x_to_5.0

Thans dcsapak for your answer.
To upgrade from v4.3 to v4.4 i just need to
move live VMs out,
apt-get update && apt-get dist-upgrade on an empty host
and that's it?

Yes, that should be all. And reboot the node afterwards of course.
