domain change = license change?

So if I change domain names on my server ( albeit just from localhost to mydomain.com ) do I have to transfer my licenses or is there another way? Granted, I just have the free licenses so its not a major concern but I'd still like to know for future reference.

If you have free licenses just generate a new set.  It's not worth the time you and Boonex will spend to transfer them.  If you have paid licenses, then contact Boonex Sales Support (LlyubovL) and she will transfer the licenses for you.
