Create A Temporary VM On Destination Hyper-V Server 2. Connect Temporary VMs HBAs To FC Fabric Using WWPN B 3. Verify Temporary VM Has Connectivity To Shared Storage 4. Complete Normal VM Live Migration (copy memory etc..) Limit IO Queue Depth To 1 5. Pause Source VM 6. Change Temporary VM To Permanent VM and Start IO 7. Logout of FC Fabric and Delete Source VM
