Migrate VMs from one single host to another single host?

Hello forum I have a "downgraded' Proxmox cluster (= only one node remaining) with 12 VMs and about 1.5TB data.
As storage I use LVM with raw-devices.
I would like to migrate those VMs to a new Proxmox host with more storage capacity to shutdown the old Proxmox node.
The 2 hosts do NOT share any storage.
Is there an easy way to do this?

I already tried (with another test node) to add it to the old cluster and the use the "Migrate"-function. But this does not work as there is no shared storage.
Also the "Move"-function of the vHDs cannot be used across hosts.

I already thought about to add the new host to the old cluster, add a shared NFS-storage, move vHDs from local storage of old host to NFS-storage and then back to local storage of new host.
But this requires twice copying ...

I think, copying the LVM LVs to new host would be not that difficult (dd if=/dev/mygroup-mylv | ssh 192.168.x.x dd of=/dev/newvgroup-newlv), but how do I get the configuration (including MAC-addresses!) of the VMs to the new host?

BR & thanks lousek
