Have not been able to upgrade from version 1.7.3 to 1.8.

Using web matrix I created a new website on my local machine. I then gave administrator permissions to the super user in the existing website. and then copied the media, modules, themes and App_Data directories from the existing to the new website. (As described here)

I get the error:
The resource cannot be found. 
  Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is spelled correctly. 

 Requested URL: /admin
What am I doing wrong?
