permalinks won’t upgrade to new domain adress

Hi,

I developped a site usaing wordpress on a development url like: wordpresse.mysite.com, while the old site was still up at http://www.mysite.com

Now the wordpress site is going well so I wanted to put it online, so I transfered the files in the main directory after cleaning it up. I could now access my main wordpress page at http://www.mysite.com

Problem is that if I click on an article, the link shows an error since the permalink still is at wordpress.mysite.com/article

How can I change the wordpress.mysite.com to http://www.mysite.com in the permalinks? I’ve browsed a while in the forum and haven’t see, to my notice, any indication on this particular problem. I thought things would update automatically, but it doesn’t.

Anyone can help? Many thanks.
