Copy VMs with multiple virtual disks on Xenserver to new SAN SRs

I have purchased a new DotHill SAN to replace my aging LeftHand SAN. The host is running my VMs is Xenserver 5.6 SP2 (free version). I have done some research to has lead me to believe that shutting down the VM and doing Copy VM with a full copy seems the most straight forward way to complete what I want to do.

My issue is the my Exchange server, SQL server, and File server have multiple virtual disks. For example, my File server has 3 virtual disks attached to it that are provided from the LeftHand SAN and are connected to the host as 3 separate SRs. After I have created and attached the proper sized SRs from my new SAN how do I copy those servers with multiple virtual disks to their new SRs from the LeftHand SAN.

Or am I completely wrong and need to go a different direction?

THANKS!
