Move volume with Exchange data from Disk 0 to Disk 1 within same virtual machine

Hi:

I have a Windows Server 2008 R2 virtual server running Exchange 2010.  Disk 0 has C: volume (Windows install) and D: volume (Exchange install).  Though Exchange is installed on D:, C: still contains C:\Program Files\Microsoft\Exchange Server\V14\TransportRoles\data

I need to increase size of C: volume.  I can easily add unallocated space to Disk 0 but Windows will not allow me to Extend C: to non-contiguous space.  I have read of 3rd party products that will extend C: in this case but am leary.

So, I figure best configuration is to create/add a Disk 1 from the virtual datastore, then move D: volume from Disk 0 to Disk 1.  How do I move D: volume with Exchange install?

Thank you!
