Moving Physical Cluster into Virtual Cluster

Hello All...........I have a Physical SQL Cluster 1 cluster1.domain.com (Node A andNode B) using SAN A.  Physical SQL Cluster containsthree-3 instances.

I have built a Hyper-V Failover Cluster and upon it I have also built a Guest/Virtual SQL Cluster 2cluster2.domain.com (Node A and Node B) using SAN B.

Now, I want to move the instance/databases from Physical SQL Cluster 1 cluster1.domain.com to Guest/Virtual SQL Cluster 2 cluster2.domain.com.  Is this supported?

Or do I have to add the Virtual Nodes (NodeC and NodeD) to cluster1.domain.com and then failover theinstances/database to new virtual nodes and then remove the Physical Nodes (NodeA andNodeB).

Also, confused as to how would I manage the Storage as old Physical SQL Clustercluster1.domain.com uses SAN A and I have new Virtual SQL Clustercluster2.domain.com on SAN B.  Would I be requiring to change the instances/databases location as well?

Any help on this would be appreciated.
