Integrate ckeditor 3.3.x and ckfinder 2

I was using http://www.yiiframework.com/extension/ckeditor/ since this extension released. But now I want to upgrade my ckeditor to v3.3 and ckfinder to v2 where this extension not supported.

How to reconfig this extension or there is had been a simply way to implement this lastest ckeditor and ckfinder in _form?

Thanks
