Hyper-V R3 Storage Migration

VMWare has had Storage VMotion available as an option for a while now and with SCVMM 2008 R2 Microsoft added Storage Quick Migration.  Storage Quick Migration worked well but there was downtime involved and it wasn’t an ideal solution.  In Hyper-V R3 Microsoft has added the ability to live migrate storage.
Select Move and the Move VM wizard will begin.  Select the type of move you want to perform.
Next select how you want to move the storage.  You can consolidate all the VM files to a single location, split the VM files to different locations or move only the VHD files.
In this sample we are moving all the files to a new location.  Specify the location and continue.
Depending on the size of the VM, the speed of the disk subsystem and host utilization this can take a few minutes.  But don’t be afraid as the VMs will continue to run as this process takes place.
