To uninstall Primavera’s Web Application 6.0, P6 Web Access version 6.1 and later 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.
For 6.1 and earlier installations, remove the current "myPrimavera" deployment.
For 6.2 installations, remove the current "primaveraweb" deployment.
If you will use the same p6home directory for the new deployment, delete the existing WAR or EAR file from that directory to avoid conflict with the new p6.ear file.
