How to COPY/MOVE between 2 different W2K12 R2 FAILOVER CLUSTER

Hello,

I'll have to perform a migration from different Cluster (From Cluster A to Cluster B)

Both cluster are quite similar and Virtual Machine migration using  SCVMM is working. 

But  that migration is done through 2 different datacenters (WAN), and when migration is done we will have to virtual machines IP, etc... (but this is another battle)

The question is that we would like to perform a Virtual Machine "copy" instead of perform a Move, the reason is that we would like to have a quick way to perform a Rollback in case of problems.

Move with Move-SCVirtualMachine it's easy, but there is no 'Copy' function.

I may work using some export/import techniques and recreate the VM resource on the target Cluster, but it requires some time and specific scripting.

Does anybody have any idea suggestion about how to do it?

Thanks in advance.
