I knew it was due round about now, but didn’t have a firm date, but now it’s here, and ready for you to download from the Microsoft Connect site.

What’s new in the Release Candidate?

I blogged about the key features a few weeks back, but one feature that’s been mentioned on a few blogs around the web is the Storage Migration capability that SCVMM 2008 R2 RC provides, in comparison to say, Storage VMotion (within the Enterprise SKU) of VMware’s vSphere platform.  Needless to say, it’s the same voices that piped up when Quick Migration was in 2008 Hyper-V, and not Live…

Anyway, what are the key differences between SCVMM Storage Migration, and Storage VMotion?

Well, Storage VMotion allows transferring of the VM's storage with no downtime, and it's a great technology, whereas Quick Storage Migration does introduce a little downtime to that VM, however SCVMM's Storage Migration capability is built into all versions of SCVMM, including the $500 workgroup edition, so it's a feature that's available to a vast majority.  Will QSM become Live Storage Migration in the future?  I can only assume, but who knows.  Now that we have the Live Migration capability in Hyper-V, translating that across to Storage shouldn’t be beyond comprehension.  As I've said, currently, on the QSM side however, the caveat to be aware of is the introduction of a short period of downtime (saved state) of a VM as it’s storage is migrated.

(Thanks to Bjorn for the correction!)

Download it from Connect.


  • i do not fully agree on this.

    storage vmotion can also migrate the vm to a new host along with the storage.

    additional licenses is true, but on the other hand all the customers who has storage vmotion have an enterprise license and can continue using this feature.

  • Hi Bjorn,

    Thanks for the update - I got the image from here ( - I've adjusted the post accordingly.

    Can you migrate the Snapshots too?
