title: move a virtual machine from one vCenter to another vCenter
body: <p>I have the following problem: 
  There two separate vCenters (ESXi). They cannot see each other or communicate in any way.
  I can create a Clone of a VM in vCenter1 but then I want to move that Clone in vCenter2.
   Is there a way that I can copy the Cloned VM (files) on an external HDD and move them in the other vCenter?</p>
