I am trying to migrate some VM's to a new Hyper-V server and have run into a problem with versions differences and can't figure out how to fix it. I did apply 2 updates to fix a DPM problem a while back but don't remember what they were. The info is below for the error. Does anyone know the hotfix I need?<br/><br/> Unable to migrate the virtual machine xxxxx because the version of virtualization software on the host xxxxx.xxxx (6.0.6001.18221) does not match the version of virtualization software on the source host (6.0.6001.22383). To be migrated, the virtual machine must be stopped and should not contain any saved state. <br/>© 2009 Microsoft Corporation.

However, you should be able to migrate the vm as long as it is stopped, not paused or saved.<a href="http://support.microsoft.com/kb/967902"><br/><br/><br/>http://support.microsoft.com/kb/967902</a><br/><hr class="sig">BillSun, 05 Jul 2009 00:27:20 Z2009-07-05T00:27:20Zhttp://social.technet.microsoft.com/Forums/en/winserverhyperv/thread/c50f4dc3-9e4b-4ee9-bc84-4aaff661cf4b#6d23947a-36cf-436c-afc6-55176e597dafhttp://social.technet.microsoft.com/Forums/en/winserverhyperv/thread/c50f4dc3-9e4b-4ee9-bc84-4aaff661cf4b#6d23947a-36cf-436c-afc6-55176e597dafmtnman1000http://social.technet.microsoft.com/Profile/en-US/?user=mtnman1000That was it.
