Windows Server 2012 Hyper-V Installation and Configuration Guide

Upgrading Hyper-V

Windows Server 2012 was announced on September 4, 2012, and from then on, all these great features became available to everyone. If you’re still using Hyper-V on Windows Server 2008 R2 or even Windows Server 2008, you probably are planning to upgrade your own hosts to the latest version.
