You are trying to migrate a virtual machine to a host that is running Windows Server 2012. After this migration, the virtual machine cannot be migrated back to a host running any earlier version of Windows Server. 

If the version of the virtualization software on the destination host does not match the version of the virtualization software on the source host, the saved states will be removed from the virtual machine and its checkpoints during the migration.

Do you want to continue?
