I currently have a site hosted that i've developed in Joomla. I decided to use a "temporary" domain name for this site as i built it and now that i'm ready to move my "official" domain name from its current site to the new Joomla site.

What do i need to do to the Joomla configuration to accommodate the new domain and what do i need to consider with respect to my components (JCal Pro, JomSocial, Kunena being the big 3). Not sure if it matters, but my host is Rochen.

Thanks for your help. (Still a noob but learning)
