Upgrade Readiness Tool (URT)

Cisco ISE Upgrade Readiness Tool (URT) helps detect and fix any data upgrade issues before you start the upgrade process.

Most of the upgrade failures occur because of data upgrade/corruption issues.

The URT is designed to validate the data before the upgrade to identify, and report or fix the issue. If the URT fails it will create a file which can be shared with TAC for further troubleshooting.

The URT can be downloaded from the ISE download page on Cisco. The URT tool can be run on a Secondary Administration Node (PAN), for high availability and other deployments with multiple nodes, or on the Standalone Node for a single-node deployment. There is no downtime for running this tool.

⤷ The following prerequisites are checked by the URT tool:

  • Version compatibility;

  • Persona checks;

  • Disk space;

  • NTP server;

  • Memory;

  • System and trusted certificate validation.

#1) Upload the files to the SFTP server from your laptop.

In this example, you already have a repository configured! 🕶

#2) Install the Upgrade Readiness Tool.

Once the URT has finished all the checks, we should be able to see the time estimate for the upgrade. If you get all "successful" message, the actual ISE upgrade should go smooth.

#3) We can now remove URT from ISE.
