Will Unregistering a VM from one host and re-registering it onto another host cause any issues with VM Backup like Veeam?

If I unregister a VM from one Host, and then RE-register it to a completey different host, does it receive a new GUID? or whatever and potentially cause issues with Veeam backup of the VM for example?

The reason why I ask is because I am tasked with migrating VM's this way since there is no absolutely no other option available and I need to get certain VM's off of one host and onto another.  My only concern is perhaps the GUID of the VM or its ID will change and cause issues with Veeam backup.  Is this a valid presumption?

Unregister and Re-register will cause the Managed Object Reference ID to change, this is what Veeam uses.

Veeam will likely create a full backup or fail... - https://www.veeam.com/kb1299

see my EE Article here about UUIDs etc (which don't change)
