URL Redirection Problem

Hi!
Recently I have changed my domain name and having some errors. Means old posts are showing old domain if someone came from saved old URL.
For example:

http://www.money9.net/admaya-review/

– This is a post with new domain name and the old post was

http://jobinformative.info/admaya-review/

Now if someone clicks on the second link, then its showing the

http://jobinformative.info/admaya-review/

instead of redirecting to

http://www.money9.net/admaya-review/

Also, in the popular post widget, all links are pointed to old domain.

My Old Domain: http://jobinformative.info
New Domain: http://money9.net

Please suggest something!
