transfer to another host

Hello
I would like to buy the pro version of gmap but I'm now updating an old site built in joomla1.5 to joomla 3.2.
When I'll move this site to the host from my test host the address and the domain name will change a bit because now is a subfolder of my main domain
It is possible to validate the extension after moving site on the new host with the final address?
Thanks in advance for answer
