Is it possible to upgrade to Windows Server 2012 R2 from Windows Server 2008 R2? Our Windows Server 2008 R2 has a valid license key.

I do not have the installation media for Windows Server 2012 R2. If I download the Windows Server 2012 R2 Evaluation installer, will it recognize my Windows Server 2008 R2 license keys?


For the first question, Yes, but some of the configuration will lost.

For your second question, sadly, your Windows Server 2008 R2 licence cannot be used to activate a copy of Windows Server 2012 R2. And the evaluation installer may not contain the image of a retail or volume licencing version installer.

    So does this mean that I have to buy a new license for the newer Windows Server OS? – F0r3v3r-A-N00b Apr 10 at 9:44
