How to handle license when duplicating entire website I have two seperate clients on different domains but I'm developing very similar websites for each. If I duplicate the entire site and upload to new domain what is the best way of handling the license key for the duplicated site. 

I'm assuming if I transfer the license, using the control panel message, then the other website's license will break.

Any help would be appreciated. 

(edit: I want to pay for the license on the duplicated system without losing any data.)
I think it would be enough to delete the license.key file under

craft/config


and purchase a new license. The key file will be re-generated.

Some more info in this answer, and here is how Craft decides if it is running on a public domain
