How to upgrade JDeveloper11 to 12c?

I have downloaded Oracle JDeveloper 11.1.1.7 (jdevstudio11117install.exe) for developing ADF/MAF Mobile application, I want to upgrade the JDeveloper version to latest.

It is possible to upgrade/update the latest version? or Should I need to download latest freshly. Please suggest.

Solution

I suggest to download a fresh copy of JDeveloper 12c.

JDeveloper 11.1.1.* has a wizard for updates, as shown on the image

but you can see that is stated that it can apply updates only for JDeveloper 11g (which probably means that it cannot automatically upgrade to 12c).
