Use the URT in order to detect and fix any configuration data upgrade issues before you start the upgrade process. Most of the upgrade failures occur because of configuration data upgrade issues. The URT validates the data before the upgrade in order to identify, and report or fix the issue, wherever possible. The URT is available as a separate downloadable bundle that can be run on a Secondary Policy Administration node or standalone node. There is no downtime to run this tool.
