[ovirt-users] migrating via pivotting the storage domain between instances of Manager

Is it possible to "pivot" up or down guests from one instance of Manager to another instance of Manager by detaching the data storage domain from the source Manager's data center and attaching it to the destination Manager's data center? I tried this with a block type storage domain, but there are no storage domains found when I do "import domain" in the destination Manager. If I do "import domain" on the source Manager and choose the same oVirt host to perform the import then the detached storage domain is able to be imported. If I re-attach the storage domain to the source Manager's data center the unregistered guests are available for import. Why does this require that the oVirt host performing the import be the same host that had formerly mounted the domain? Or, is it that the host is still recognized as enrolled in the DC that had created the unregistered guests on the detached storage domain? What if, instead of detaching the storage domain from the source Manager's data center, I shut down all guests and put the oVirt host in maintenance mode and enroll that same oVirt host in the destination Manager's data center, then would it be possible to import the detached storage domain and import the unregistered guests and templates stored there?
