Move porxmox configuration to a new h/w

I'd try to just move over the installation disk/drive to the new hardware.
AFAIK there is no backup/restore process for a PVE host itself. IMHO: lack of functionality. I was using image backup/restore up until now.
 
funny how i was just having the same issue. my plan is to clonezilla the drive and just put into the the new hardware ...in case something goes wrong i can still stick the copy into the old box and things will work out. once its running you can simply move on.
 
Clonezilla should work as well. I was using identical disks (8GB SSD) and DD for many years now as a backup/restore method
