However, perhaps someone can clear this up for me: With XenServer, we are able to migrate a VM and its volumes from a host using a shared SR in one cluster to a host using a shared SR in another cluster even though the source host can’t see the target SR.
Is the same thing possible with VMware or does the source host have to be able to see the target datastore? If so, does that mean the target datastore has to be zone-wide primary storage when using VMware to make this work?

Since filerTo.getUuid() has the UUID for the target datastore, that works for morDsAtTarget, but morDsAtSource ends up being null. For some reason, we only check if morDsAtTarget is null (I’m not sure why we don’t check if morDsAtSource is null, too).
