A friends website has been stagnant the past few years and they have version 2.6 on their website. What is the best way to upgrade to the newest version without worrying about too many problems?
We have a configuration setting mapping between FCKeditor 2 and CKEditor 3 (this will be largely the same in CKEditor 4).
What you choose to do really depends on how customized your FCKeditor was and how much you want to preserve those customizations. The best bet is to backup the FCKeditor installation, then choose a CKEditor 4.x package that best suits your needs, and install it as a fresh install. After you are done, you can simply customize your CKEditor 4 as you wish, either to mimic your FCKeditor customization or to make use of its numerous features that were introduced since the friend's website was last upgraded :)
