Upgrade after license ended and domain change questions ?


I bought a Xenforo license a while ago for a domain name that is not in use anymore (forum has definitively closed). The license has now expired.

My questions are :
  • If I would like to get again a valid license am I entitled to the upgrade price (40 $) ?
  • If yes, will I be allowed to transfer this license to a new domain ?
Thank you for your answers :)
Sorry to piggyback on this question, but its pertaining to a similar change:

If I were to move my XF from one name to another, could I change both the site title and site URL via the Customer area, or just the domain?
