EXPERT RESPONSE
You'll need to migrate it all along with the operating system. This is where good capacity planning (including a performance model for the disk architecture) should encompass the storage design behind the virtual machine (VM). You'll need to consider not only the disk allocated, but some performance characteristics around ensuring that page/swap or application data is best presented to the VM from the networked storage array.
