I've done a attach upgrade from a 2007 db to 2010 following the MS guide and all went ok.
However, I have no idea what to do next. When I navigate to the root web page I just get the default site, not the new one I just attached.
So, I remove the previous database from central admin and then I get a HTTP 404 error page only.
Do i need to do something in IIS or have I missed something in the upgrade or something? BTW, as you can probably tell I'm a complete newbie at all of this.
