Setup and Upgrade
My local setup consists at least of a Windows XP Pro machine running IIS 5.1, SQL Server 2005, and the .NET 2.0 Framework.
There are 5 basic steps to a clean install
Download the .zip file from dotnetnuke.com.
Create the database and a SQL Server login
Create the website folder and unzip the downloaded .zip file.
Create virtual directory in IIS and configure the website
Run the DNN install wizard in your favorite web browser.
In general, upgrading DotNetNuke is a straightforward process. It is accomplished simply by copying the files for a new version over the top of an existing version and allowing the application to guide you through the upgrade. Having said that, there are of course lots of specific scenarios, consideration of 3rd party or custom modules, high traffic sites, etc. And so any extra steps in the upgrade process are in consideration of your site's particular circumstances. But it is important to understand that the basic approach to upgrading is as simple as copy & replace.
