Switching from Core to GUI is quite simple in Server 2012. But not when upgrading.
- Windows 2008/2008 R2 Full Server can only be upgraded to Win 2012 Server with a GUI
- Windows 2008/2008 R2 Server Core can only be upgrade to Win 2012 Server Core
After the upgrade is finished it can easily be switched between Core to GUI.
