I am undergoing a business name change. This is a probelm when it comes to my site as my domian name will be changing.

zencart uses hard coded links ie http://www.mysite.co.uk/index.php?main_page=contact_us and not relevant links like ./?main_page=contact_us

this poses a probelm when i come to change the domain on the site. is there a way inwhich i can chane the link to a relevant link so that i i can use my new domain and my old domain??

or how do i go about changing the domian on zencart so its no longer uses my old name and uses my new name/domain??
