There is no reason to be disappointed ;-) If you use shared storage, you can simply
move the configuration file like:

# mv /etc/pve/nodes/<oldnode>/qemu-server/<vmid>.conf /etc/pve/nodes/<newnode>/qemu-server

That is really simple. But please make sure that <oldnode> is really offline (else you have a serious problem
because 2 VM access the same shared storage location).
