hi,

i would change a old node to a new. i would use same name and ip adress for node. what are steps to make it.

is this node in a cluster?

if it's a cluster member:
* before deleting the node from the cluster you should migrate the guests away to other nodes
* after all the guests are migrated, you can delete the node from the cluster using the GUI or pvecm CLI tool (check out this section in our admin guide [0])
here you should pay attention to:

After removal of the node, its SSH fingerprint will still reside in the known_hosts of the other nodes. If you receive an SSH error after rejoining a node with the same IP or hostname, run pvecm updatecerts once on the re-added node to update its fingerprint cluster wide.

* once the node is deleted, you can reinstall the new PVE version on it and add it back into the cluster

hope this helps!

i've replied in that thread now, please try removing the vmdk or converting it, then the VM should migrate fine. if the solution works please mark that thread [SOLVED]
