Upgrade to APEX 4.0 - Known Issues - Workarounds and Patches

If you upgrade your application from APEX 3.x to 4.0 you might encounter some issues.

At ODTUG I did a live migration of an application written in APEX 3.2 to 4.0 and I talked about some of the issues I discovered and how I worked around them. I’m doing the same presentation at APEXPosed in Brussels in October. You also might have seen my previous posts where I upgrade DG Tournament from APEX 3 to 4.

On the Known Issues page you see the issues categorized nicely. If the issues can be fixed by working around it, it’s also mentioned there. Oracle is working hard on a patchset (4.0.1) and they hope to release it soon. On Metalink you can already find patches for specific issues too.

I plan to write some other blog posts with steps I did when upgrading DG Tournament (site no longer online) to APEX 4.0.
