shut down whether you are going between SANs or DAS datastores is just a matter of time.</div><span class="HOEnZb"><font color="#888888">

for supported vMotion methods all said “when shared storage is available”… and my question was “well… what if you have no shared storage and need to migrate between such datastores and hosts? Is this supported?”<u></u><u></u></span></p>
