Can you detail version impacted and first version where bug resolved?
Or a bugzilla number?

The VM was runnig when doing the disk migration and didn't get any problem.
In the gui it appears that the VM has the new LUN as the backing storage

Yes. And one more was generated with description:
 Auto-generated for Live Storage Migration

VM has only one disk. Overall snapshot now
