    Upgrade from to fails


      I am trying to upgrade my Jdeveloper from to The installation fails with the message: "The product maintenance level of the current installer (Jdeveloper and ADF: is not compatible with the maintenance level of the product installed on your system (Jdeveloper and ADF: Please obtain a compatible installer or perform maintenance on your current system to achieve the desired level".

      So i wonder:
      -what is maintenance level?
      -is there a compatible installer? If yes,where?
      -how do i perform maintenance on my current system to achieve the desired level?

      Please, i need some help to fix this. I am trying to convince my customer that Jdeveloper is the right tool and i get stuck on what i thought was a simple upgrade.
