‘Storage Migration’ is a very handy function in SCVMM 2008 R2. With this tool, you are able to move the VM storage (configuration file and VHD file) from one place to the other with minimum downtime (less than 1 minute).
This diagram illustrates how the storage migration works.
This function is simple to use, just right click the VM in the VM inventory and click ‘Migrate Storage’.
Select the target storage location for both VM configuration file and VHD file, click ‘Next’ then choose ‘Move’.
In the job log, you can track the progress of each step. The most time consuming one is the step 1.5, in which the host uses BITS to copy the VHD file from source to destination. If you don’t have a high speed network, it will take for a while.
