changing sites

I currently have a site that I was about to drop but, decided since I already paid for the hosting that I might as well try something different. I am purchasing a new domain name but, what are the ramifications if I leave everything intact, change the domain name, delete a few forum threads but, leave the current member base... I guess what I am trying to say is what changes need to be made to vbseo to usher in the change...?

You need to create a support ticket and request update on your license. However we strongly advise our users not to change their established domain name as changing domain is like starting all over from the beginning.
