Right now I have a site that I'm wanting to upgrade to DNN4, however, its acting kinda funky.  I changed the ASP.NET version, copied DNN4 over the DNN3 install, and renamed the web.config to OLDWeb.config, renamed release.config to Web.config and then copied the ConnectionString stuff and MachineKey from OldWeb.config to Web.config.

The first time I went to the site, it upgrade, however, whenever I try to go to the /Default.aspx it just redirects me to the install page and it says "nothing to install".

Am I missing anything?

ad this to the appSettings section of the webconfig

<add key="InstallationDate" value="todaysdate" />

where todays date is really todays date. (I usually use yesterdays date)

Thanks a ton.  That ended up fixing the problem.

Why do we need to keep track of the install date though?
