Suite Possible to change MySQL database hostname after install?
 

I'm doing a fresh/new vBulletin install on our new host which our domain is NOT pointed to yet. There is a temp subdomain set up there and the host control panel won't let me use our hard IP address, only the subdomain. If I set up the database this way what is involved in changing it once we go live and change to our regular domain? Also, any way to force it to use the IP rather than the subdomain? (using DreamHost)
