I would have given you the same instructions as Lynne but seeing as the site was already installed opening phpadmin and editing the settings table would have been much easier. Ofcourse if doing it from the start you should change the domain settings before backing up and moving.

For next time:
It(phpadmin) should be an option on your server. You just log in using the same database info you entered in your config file. Once there you see the list of table in alphabetical order on the left side. Scroll through until you see the settings table and then click on it and choose "browse".. Then scroll through looking for your url, change it to your new one where ever you see it. Simply click on the url and enter your new one.. Bam.. done in about 30 seconds. Much easier then switching back to your old domain, changing the admincp, backing up and then reimporting.
