Gather Upgrade Properties
This section describes all of the options in the Gather Upgrade Properties phase for upgrades from 10.x source systems.
This phase provides the user with different options to configure upgrade tool and run it in a specific manner. The following screen shows the Windchill Upgrade Manager at this phase:
The screen is divided into tabs and each tab contains various input fields to collect information from the user. The following describes each of these tabs and the input fields associated to each tab:
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.
Perform the following steps to use the file output by the Upgrade Property Viewer WinDU task:
1. On the target system, create the GatherUpgradeProperties folder in the following location: <Windchill>/Upgrade/UpgradePhases.
2. Copy the autoUpgrade.properties or the ReviewedSourceUpgrade.properties file from the source system to the following location on the target system: <Windchill>/Upgrade/UpgradePhases/GatherUpgradeProperties/.
3. Rename the autoUpgrade.properties or the ReviewedSourceUpgrade.properties file in the target location to upgradeUser.properties.
