Now that there is no longer any support for PHP with CKEditor, I find myself stranded. I read that the old PHP classes would work with 4, so I dropped the old PHP scripts into a clean install of 4.2, and was happy to find that I did at least end up with a working instance, however it's a very shallow interpretation of "working". Most of my config settings are being ignored, and none of the javascript patches I needed work any more and the APIs have gone away - I will need to port them to ACF instead. If the PHP classes are not going to be supported any more, I really don't want to have to maintain them either. This means I need to pick apart everything they do and reverse-engineer the config and JS scripting they generate (since it's all undocumented) in a way that won't break my app. So I'm facing probably a couple of weeks of pointless pain in the face of no documentation - the upgrade guide amounts to "it should just work". There's a ton of detail in the docs, but it feels like examining an elephant with a microscope. So much has broken or disappeared, but there's just no breakdown of what's gone or what should be done instead.
Is there any better info on doing 3 to 4 upgrades?
