Live Failover – Does this create new Vmware Machine ID’s in the Vmware database? Customer has programs like backup that rely on Vmware Machine ID.

Yes when you do a Move, Failover Live or Failover test a new Vmware ID is created. I know backup software like Veeam rely on this ID and when the machine is failed over to the recovery side the backup jobs fail due to their reliance on that ID.
I wanted to add some more information regarding the preservation of a BIOS UUID of the protected VM.
Please have a look at the following documentation in section 5 –
