Kanopi Studios' Senior Drupal Engineer Shiraz Dindar advises Drupal 7 site administrators to upgrade from CKEditor 4 to CKEditor 5 due to the former reaching end-of-life, which stops updates, security patches, and new features. The upgrade, necessary despite Drupal 7's extensive use, is complicated as direct update paths are lacking. They share a successful approach using a patched WYSIWYG module instead of the traditional CKEditor module, detailing the process and challenges faced, especially with image uploading within the editor. This guide is crucial for maintaining secure and functional Drupal 7 sites.
