</span>Storage is defined on a data center level, not on a host level, so you are<br>
correct you cannot have local storage and shared storage in the same data<br>
center.<br>

<br>
</span>Yes, if you go to the disks main tab, you can select the disk you want to<br>
migrate and click 'move'. This will give you a dialog that allows you to<br>
select the target storage domain and profile.<br>

<br>
</span>See above answer, you can live migrate between storage domains, and since<br>
storage domains are at a data center level if both hosts are in the same data<br>
center, and both storage domains are in the same data center, you can live<br>
migrate the storage as well as the VMs. It will be 2 separate operations<br>
though.<br>

<br>
</span>Since these hosts cannot be in the same data center (cannot mix shared and<br>
local storage) that is the only option I know of for this particular scenario.<br>
