Cross-Version Live Migration

… finally an easy way to migrate Virtual Machines accross different versions of Windows Server Hyper-V.

The first step towards this was done by Microsoft when giving us the possibility to do a Shared-Nothing Live Migration.

Introducing Windows Server 2012 R2, this feature can be used in order to migrate Virtual Machines from a Windows Server 2012 Hyper-V Host to a Host running Windows Server 2012 R2.

Of course this is not only possible for single Hosts, but also for migrations between Clusters.

Now you don’t have to worry about a maintenance window for migrating your Virtual Machines to a new system, you can do a Cross-Version Live Migration 🙂

Note: It’s not supported to perform a migration from 2012 R2 to 2012.


I'm a Systems Engineer working for an IT-Service Provider in Frankfurt am Main, Germany. I am specialized in Virtualization, High Availability, Storage- and Server Administration. In my free time, I like spend time with my lovely wife, to do sports like jogging and biking. I enjoy movies and a good bottle of fermented grape juice.
