Optional Properties
The Optional Properties tab contains the properties to enable or disable Windchill Upgrade loggers and control the amount of detail written to the upgrade log files. This option is typically used at the instruction of PTC Technical Support for advanced troubleshooting. Logs are output to the UpgradeManagerLog4j and MethodServerLog4j files located in the Windchill logs directory. The following is a brief description of each input field:
