I realized that I was looking at an old upgrade guide which was vcenter 5.0 and it supported managing 3.5 hosts. Sorry for the confusion. Anyhow, would it be possible to do any of the following options:
1) Present the FC storage to the new ESXi 5.1 hosts, shutdown the vm, browse to the Virtual Machine folders, and register the Virtual Machines on the new ESXi 5.1 hosts. After the VM gets registered assuming this works, perform a SvMotion to switch over to the iSCSI datastore?
2) Present the iSCSI storage to the OLD 3.5 hosts, shutdown the vm, browse to the Virtual Machine folders and register the Virtual Machines on the new ESXi 5.1 hosts. After the VM gets registered assuming this works, perform a SvMotion to switch over to the iSCSI datastore?
thanks,
