How to update CKEditor to version 3.6.3 ?

Hi Guys,

I have downloaded the latest version of CKEditor to upgrade it on my OC 1.4.9.1.

This is what I have done so far:

1. I have downloaded and uploaded the latest version of CKEditior to: admin/view/javascript/ckeditor
2. Copied the old config.js across
3. Clear system cache

Is there anything else I to do? Because it's not working. Thanks

Upgrade your whole OC would be better than just upgrading the editor. There are many codes to be changed
