powerCLI move-vm commandlet

Curious as to whether or not i can move just the Datastore and only the datastore with the following:

Move-VM -VM$VMobj-Datastore$destDatastore-DiskStorageFormat'Thick'

1 Anyone shine some light on this? The documentation does give an example with the -destination parameter but no documentation on how to tell it to explicitely move one aspect of the VM or if the commandlet works that way.

2 Also, the THICK parameter doesnt seem to work at all as i have moved the VMs to and from datastores and they are still Thin.

Thanks!

EDIT: Thick parameter wasnt working because the NFS i was attempting to transfer in was not in the same vcenter.

question 1 still applies
