DotNetNuke is an open-source content management system ideal for creating and deploying projects such as commercial websites, corporate intranets and extranets, and online publishing portals. DotNetNuke is built on a Microsoft ASP.NET (VB.NET) platform, and is easily installed and hosted with all of our Windows Hosting Plans. If there is an upgrade available, follow the following steps to perform the upgrade.

In Preparation:

• Back up the DNN database
• Back up all website files
• Check your database and website backups!
• Download the latest DotNetNuke upgrade package:
  a. From the www.dotnetnuke.com site. You may need login credentials if you are using a non-community version of DNN.
  or
  b. Click the "Upgrade Available" button that appears when you are *not* running the latest version.
• Create a basic html document called app_offline.htm. This page will be shown on the site while you are doing the upgrade.

See figure about no maintenance page. Users may see errors while the site is partially upgraded.

Good Example - HTML page to let users know the site is offline:

To Perform the Upgrade:

1. Upload the app_offline.htm file to the root web folder for the site.
2. Navigate to the site in a web browser and check that the app_offline.htm file is shown instead of the usual default page.
3. Copy the contents of the latest DotNetNuke upgrade package over the top of the existing files. All files should be copied because the package should only contain generic files ?no configuration files.
4. When the copy is complete, rename the app_offline.htm file to app_offline.htm.save. When you navigate to the site, you will see a new construction page:

   

5. Access the /install/install.aspx?mode=upgrade page (e.g.www.mysite.com/install/install.aspx?mode=upgrade) using a web browser. The site will begin an automatic upgrade process:
