Run the Upgrade-Mandatory Windchill Diagnostic Utility (WinDU) tasks and fix all issues that are reported. You will need to use the latest WinDU patch from the web site.

To help with entering the correct information in the upgrade manager, the pre-upgrade Windchill Diagnostic Utility (WinDU) task Upgrade Property Viewer is executed on the source system. This WinDU task gathers information about the source system and adds it to the autoUpgrade.properties or the ReviewedSourceUpgrade.properties file in the <Windchill>/Upgrade/ directory.

For more information on each WinDU task, refer to the Windchill Diagnostic Utility Guide. You can download the latest WinDU patch and the guide from here.
