About "Clean Card Arc"

CLAMP have started this manga not much time ago, that seems to be a sequel to the original Cardcaptor Sakura manga, and I've seen it in my local comic store.
I wanted to buy it -since i adore CLAMP's art style, and wanted to give Cardcaptor a chance- BUT then I remebered this is a SEQUEL from a manga/anime I haven't read/seen,

So, here comes my question: is it necessary to read the Clean Card Arc manga to have read the previous Cardcaptor Sakura? Or can it be enjoyed without previous knowledge of the franchise?
Also, feel free to comment what you think about this new story, if you liked it, what did you expect from it, etc.
