If you have CMPro v4.0 or v4.10 and wish to upgrade to the new, Eolas Patent-compliant, Mozilla-compatible editor found in v2.20, these instructions are meant for you.

1. Remove these files from the web root as they are no longer necessary:
• browse.cfm
• browsefile.cfm
• upload.cfm
• uploadfile.cfm
   
2. Delete the current /fckeditor/ folder and all of its child folders.
    
3. Place the new /FCKEditor/ folder off the web root.  Note this file set is MUCH larger; effectively doubling the size of the CMPro distribution.
    
4. Replace the following files with those in the current distribution:
• /cmpro.css
• /admin/inc_editorcall.cfm
• /admin/includes/inc_menustyles.cfm
• /admin/admin_boss.cfm
• /admin/content_boss.cfm
• /admin/cmproadmin.css
• /admin/content_itemedit.cfm
• /admin/tags/tag_sectionpaths.cfm
5. Copy the styles you want to have show up in the editor's style window into /fckeditor/editor/css/fck_editorarea.css.
    
6. Write the styles you will use from Step 5 into /fckeditor/fckstyles.xml, using the current file as a guide (the original 2.2 distribution has a much broader example.  The CMPro version only ties in the styles from a style sheet).
