* You will need to repeat the following steps for each VM
:# Shutdown the VM on the old host.
:# Create new VM on the new host with the same ID and Disk size as it is on the old host.:# Navigate to the shared storage and rename the disk image to corresponding VM to match. (Note the 1 & 2 in the file names.)This can become very confusing, thus the need for a solid backup of the images.
:# Delete the "pseudo" disk image only after you have verified that the VM has booted successfully on the new host.
* Once you have all the VMs up and running on the new host you can now shut down the old one and install the new version of ProxMox on it.
