Change license from testing site to live site

I've just completed developing a site for a client and moved it from a testing/development URL to the live URL for the client. Now when I go to updates in the extension manager it says that the site is licensed to example.domain.com instead of the live domain chspharmacy.com . How do I change the URL in the configuration of Hikashop to recognize the correct domain? The correct domain is configured in my account on Hikashops website.
