Migrating large VM from one host to another with Quick Migration

[importantchicken562]

Hi all,

I have a single-host vSphere environment with a large VM (~5TB) that's backed up nightly via Veeam B&R. I need to migrate this VM to a new host, and my plan was to use Veeam's Quick Migration feature.

My main concern is avoiding a new full backup after the move. I ran a test: shut the VM down, performed a Quick Migration, and left the "delete VM from source host" box unchecked — I wanted the option to boot the original VM again if the migrated copy didn't come up cleanly. But because I left that box unchecked, Veeam treated the VM on the new host as a brand-new object and kicked off a full backup instead of continuing the incremental chain.

What I actually need is a way to move the VM to the new host while Veeam still recognizes it as the same VM and continues backups from where the last one left off — ideally without losing my safety net of being able to fall back to the original VM if something goes wrong.

Has anyone dealt with this? Any advice on how to preserve the backup chain through a host migration like this would be appreciated.
