… 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.
