To uninstall P6 Progress Reporter from a WebSphere server:
Do one of the following:
On Windows platforms, from the Start menu, choose Programs, app name, Uninstall app name.
On Unix platforms, change to the installableApps/app name directory under the WebSphere install directory and run the uninstallws.sh script.
Launch the WebSphere Application Console.
Remove the current "pr" and "pr-help" deployments.
If you will use the same prhome directory for the new deployment, delete the existing EAR and WAR files from that directory to avoid conflict with the new pr.ear and pr-help.war files.
