(In reply to Roman Hodain from comment #0) > Expected results: > The preview is migrated as well or the operation is not allowed. It should just be blocked. Tal, since this is your week, please take a look, and either fix it or reassign at your discretion.
Storage migration both live and cold is now blocked by CDA when one or more of the VMs attached to a disk are during a snapshot preview or during a snapshot creation
Verified on 3.6 master, the operation is now Blocked
