Windows issue — moving blog folder from outside to inside .net web app

In a .NET web app, I have a link to a WP site. It works fine except users get the “This page contains both secure and non secure items” warning (IE7) before the blog opens. I should have installed WP INSIDE the .NET site, but I didn’t. So I’m going to move the WP folder to inside the .NET site.

So I have a question: WP supports “WordPress address” and “Blog address” on its admin General Settings page. I want these to be the same, but I want to move them to a new folder entirely (a folder inside the .NET site root). Is it any different doing this from upgrading to a new version? I.e., do I simply move everything and run wp-admin/upgrade.php from the new location? Obviously I’m worried about screwing up a config or database file/table. Thanks.
