exactly same forums, different domain name, different hosting

do i need to buy different Licenses?

[Wayne Luke]

Yes because it would be two different and unrelated installations.

So wait if I shutdown my current site and decide I want to use vbulletin on my new site; I can't ? (Keeping in my mind I will only have 1 active installation)

You can shut down (delete files) from the old installation and install on a new installation without a problem. In the Member's Area you just need to update the URL to your license, make sure it is current;
