After a little research I found on the 8.0.0 release page ( http://dotnetnuke.codeplex.com/releas... )  that PokerDIY reviewed it and had a very similar error result with upgrade (  http://screencast.com/t/H3V6PldhsP ).

In the "Additional Changes" section of the page, the third point says:

• Extracted all administration modules from the base platform so they can be installed/uninstalled separately

That implies that these modules that failed the upgrade can be installed separately. Does anyone know where the install packages for them are located?

Thanks to Sebastian I found the missing modules. When I went to install them, I noticed that they were already installed. What was missing were the pages that they used to be installed on. So I am adding each page in the Admin section and adding the appropriate module onto that page.

In the Admin menu control bar, there are three groups:  Common, Advanced and Bookmarked. All my new pages in the Admin menu are appearing in the Advanced section of the control bar.

How can I designate that a page should be in the Common section of the Admin menu?
