Deploy from test server to production PROBLEM

[raowyr]

Hi,
i have build a small website on a test server hosted on altervista.org provider. The test site is http://raowyr.altervista.org/gs2.

Now, when i completed the website, i decide to deploy on the production server. By FTP i copy the content of gs2 directory of test server into the root of production server. Here the result www.vivaiomassarosa.com.

Now, there are some problems.

1. admin control panel warnings http://www.vivaiomassarosa.com/admin
   
2. link to old test server by click on menu items and generic links (for example if you click on "Negozio" then redirect to raowyr.altervista.org)
   

How can i resolve these problems?
Thanks in advice

regards
