    Default 2008 to 2012 server upgrade error

    I am trying to upgrade windows server 2008 R2 to windows server 2012 R2 datacenter. It give me below mentioned error:

    Windows Server 2008 R2 Datacenter cannot be upgraded to Windows Server 2012 R2 Datacenter (Server with a GUI). You can


    choose to install a new copy of Windows Server 2012 R2 Datacenter (Server with a GUI) instead, but this is different from


    an upgrade, and does not keep your files, settings, and programs. You’ll need to reinstall any programs using the original


    installation discs or files. To save your files before installing Windows, back them up to an external location such as a


    CD, DVD, or external hard drive. To install a new copy of Windows Server 2012 R2 Datacenter (Server with a GUI), click the


    Back button in the upper left-hand corner, and select “Custom (advanced)”.

    Need help on what need to done

    Hi
    I think no version Windows Server 2008 SP1 can be upgraded to 2012 Server ,it has to be a minimum 2008 SP2 to get upgraded to 2012 Server or Datacenter.

    Presumably your Win2k8 server is full GUI and not core (you can upgrade core to GUI) ?
