Undeploy any applications protected by the Tomcat 6.0 version 3.0 agent.
Restore the deployment descriptors of these applications to their original deployment descriptors. (Backup files are useful here if you have them.)
Conditionally, if you are permanently removing the Tomcat 6.0 version 3.0 agent, undeploy the agent application.
However, if you plan to re-install this agent , you don't need to undeploy the agent application.
Ensure that the Tomcat 6.0 instance that is being protected by the agent is stopped.
