re: How do I go about purchasing a support license for an additional website?
You would purchase another Pro Pack. You can purchase it as many times as you need.
re: Also, I will be using a temporary URL for the additional website and will eventually use an existing URL when the additional website is ready to go “live”. How do I maintain the support license key for the additional website when it is “live” and no longer at the temporary URL.
My suggestion would be to only activate the support license keys on you “live” sites. But if you wish, you can activate them on your dev sites. You would first have to deactivate the support licenses on the dev site before moving your dev to a “live” site. After the move is complete, you can then reactivate your support licenses.
Hope that helps!
