Slim framework : upgrade from version 3 to version 4?

Question

I've a slimframework v3 application that provide REST API for an Angular application.

I want to upgrade to v4, but there's quite a lot of changes and the upgrade page, while it mention what is changing, it's pretty dry on how to make those change and get a working application at the end.

For example, it says the new App() no longer takes the settings... ok... where does the settings go now ? Likely in the Dependency Container but this is changing too. I fear that I will do a lot of code change and get a non working app and will spend ages on figuring out what's wrong.

So do you have any suggestion on how to proceed, step by step, to achieve a working upgrade from 3 to 4?

I've googled a bit, but I didn't find some walkthrough/tutorial on this subject.

I'm in similiar situation. My Slim app was coded before unit and functional tests. Now I want to develop the app tests trying to not make them independent of Slim version. After that, I will refactoring it – Dominquedominquez

I've managed to perform the upgrade. It's way too long to document it here, so I've made a blog post here :

I'll improve the article (readability & content)
