  • 2012 to 2012 R2 Upgrade

    I'm having an issue with upgrading from 2012 to 2012 R2.
    First, initially we had 2008 R2 Foundation. We performed an upgrade to 2008 R2 Standard, then upgraded to 2012 Standard. We were suppose to upgrade from 2008 R2 Standard to 2012 R2. Anyway, during the 2012 Standard to 2012 R2 upgrade, it took several hours and finally I received a message from Microsoft at the bottom of the screen
    "the upgrade was not successful. Your previous version of windows is being restored"

    Well, 2012 never restored. I waited for 1 hour and it was just at a black screen.
    So I shut down the server and booted to Last Known Good Configuration and now 2012 has been restored.

    The server is at 2003 domain functional level after the 2012 upgrade. Any recommendations on why the 2012 to 2012 R2 upgrade was not successful?

    Did you check and make sure the hardware will take 2012 R2?
