Upgrading to APEX 4.0 – it’s as easy as 1, 2, 3

When the APEX development team at Oracle recently moved to the third early adopters release of APEX 4.0, I panicked! I didn’t see the same “warning emails” that were sent with the previous transition and I thought I had lost some code that I had written for some presentations at the upcoming Kaleidoscope event.

Luckily, that was not the case. The second early adopters release was still available so I was able to export my application an import it into the new release.

During the import I stumbled upon a fantastic new feature that I had not yet known about: Upgrade Application  (previously known as the Migration Assistant)!

  1. You can see the icon available on the right after an application import.
  2. After clicking the icon you’re taken to an interactive report which lets you know which types of upgrades are available for your application.
  3. From there you can click on the number associated with the upgrade type to learn more about the upgrade and where it will be applied. Simple check the checkbox where you want to perform the upgrade and click Update. That’s it!

As you can see, taking advantage of some of the great new features of APEX 4.0 will be as easy as 1, 2, 3!
