Before you upgrade Rational Integration Tester Agent, you must stop the service. For information about stopping the service, see Running agents.
Upgrading the Rational Integration Tester Agent software overwrites the Agent.config file in your existing Rational Integration Tester Agent installation. If there are settings in the Agent.config file that you would like to preserve, for example, IBM Rational Test Control Panel domains and environments settings, you can copy the existing Agent.config file to a temporary location before upgrading theRational Integration Tester Agent software and then overwrite the new Agent.config file with the old Agent.config file after the upgrade of the software has completed.
