I understand about how the UUID can change if using "I copied".
I have migrated close to a 1000 vm's before from older vcenters to a newer vcenter and this is the first time a UUID changed.
These are windows and Linux vm's so especially the Linux vm's don't take having their UUID changed lightly
That's why I'm a bit confused. It appears like it hit a used UUID so it changed it....
Not sure....
