Site re-direct problem

I asked this question in the multisite forum and it was suggested that I should ask it here.

I currently build a test site on: cocainetreatment.jhctest.com. The site is now complete and I pointed the DNS to: cocainetreatment.info where I want it to be live. The site loads only all the links on the site still point back to cocainetreatment.jhctest.com.

I am looking for a way to avoid this problem in the future and for a way to fix this current problem? Any ideas?
