Moving SMF forum to new domain


M’kay, I have never done this before so I don’t know what to anticipate.

I presently have a forum on a subdomain that I own, hosted by dreamhost. I want to purchase a new domain hosted on dreamhost to move this forum to. Am I correct in assuming that I can transfer all of the files and redirect the forum database to the new domain or… am I being ridiculously hopeful and I will have to reinstall everything?
