MyBB Community Forums

I switched hosts recently but never got to make a backup since the host had my forum down so often because of DDOS attacks. Well I got a hold of all my forum files. I have the forum directory but how do I integrate with my new host? Do I upload all of the forum files to the cPanel then go to domain.com/install and do a fresh install? Please help this is urgent.

Install a fresh copy of MyBB normally, replace any files you need from the old ones (e.g. plugins or custom pages) and import the database backup in phpMyAdmin. That's all there is to it.
