Prescan.exe Download and Information
I have to thank Sean Livingston and Ambrose Treacy for following through. Prior to launch I pushed really hard to get prescan as a separate download. Neither of them was on the WSS team during my first attempt. After a number of fun hoops. Ambrose and friends really came through. Unfortunately I was busy with TechEd and didn't get this post out sooner.
First you can get Prescan the pre-upgrade scan tool for WSS and MOSS here:

Before you can upgrade to Microsoft Office SharePoint Server 2007 or Microsoft Windows SharePoint Services 3.0, you must run the Prescan.exe utility against your existing Web sites. This pre-upgrade scan tool scans your sites and reports issues, allowing you to fix any errors before you perform an upgrade.
If you have not successfully run this tool and you attempt to upgrade your environment, when you attempt to run the SharePoint Products and Technologies Configuration wizard, the wizard will exit and prompt you to run the tool. Please resolve any issues discovered by the pre-upgrade scan tool before the upgrade and before scheduling the upgrade.
Again, an in place upgrade will FAIL if the prescan is not successfully ran on the environment prior to upgrade. A gradual upgrade will FAIL if prescan is not successfully ran. A database attach upgrade will FAIL if prescan is not successfully ran.
For more information about upgrade, migration, and using the Prescan.exe utility, see the Microsoft Web site.
