copying a cart

Hi, I'm very new with cs-cart. I've got a client, who franchised a us ca-cart site, and need to copy exactly to their australian cart. We've got the copy of the cart, but we need to change the license to the cs-cart community edition. I was wondering if there's anyway that I can do this automatically somewhere/or replacing certain files, without actually having to built a completely new shop?

It's not that much for professional if your client is franchising a us site to another country spend the couple hundred. It's worth it!
