I have found tutorials online to perform the upgrade mentioned in the subject line and I'm assuming it worked successfully because I never ran into any errors.  However, when I browse to the 4.3.7 site, in this case http://localhost/dotnetnuke4,  it reverts back to the address for the old 3.2.2 site, http://localhost/dotnetnuke.  And everything has the look and feel of the 3.2.2 site.  Is this right or should the upgraded site look like the 4.3.7 site did.  Under host settings it says ASP framework is still ASP Net 1 and DNN version 3.2.2.  So was the upgrade unsucessful?  I was able to install the 4.3.7 to get a blank DNN4 site with no problems.  When I followed the instructions to to upgrade the "old" production db to version 4 it said upgrade completed.  It just seems that if I was able to upgrade successfully, shouldn't my site have the interface of the 4.3.7 site and not the old 3.2.2 as well as under host settings the DNN version be 4.3.7 and ASP framework be 2.x??
