    Upgrade from 11.1.1.1 to 11.1.1.2.0 fails

    676948
      Hello.

      I am trying to upgrade my Jdeveloper from 11.1.1.1 to 11.1.1.2.0. The installation fails with the message: "The product maintenance level of the current installer (Jdeveloper and ADF:11.1.1.2.0) is not compatible with the maintenance level of the product installed on your system (Jdeveloper and ADF:11.1.1.1). 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.
