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.

Caution:

• URT tool cannot be run on a Primary Administration Node.

• URT should be run on Secondary Administration Node or a standalone node.

These are the prerequisites that are checked by the URT:

• Version compatibility
• Persona checks

Note: Verify the available disk size with Disk Requirement Size. If you are required to increase the disk size, reinstall ISE and restore a config backup.

• Memory
• System and trusted certificate validation
