Updating temp url to domain on multisite

Dear multi site experts,
I have built my multisite at a temp url at Hostgator, and now I try to change my temp url to my domain http://tasteofslow.com. I have support from my host, but they also struggle to work this out in a multisite – so I try to see if any of you have further expertise.

My domain url work in the main site (changed in phpAdmin, wp-options “siteurl” and “home”, but then the links to my sub blogs. Is there any other values that need to be changed when updating the multisite installation to use your domain name rather than the temporary URL?

Thanks!
