  1. Make sure that prweb.war or the EAR file for your application server is not running.

  2. Remove each of the current versions of the applications.

    1. In the Tomcat Web Application Manager page, find the row for each application and select Undeploy.

    2. In the WEBAPPS directory, delete any remaining folders or WAR files.

  3. Copy the prweb.war file from the Pega-image\archives\ directory to the Tomcat_home\webapps\ directory.

  4. Restart the application server.

  5. Shut down the server and delete the prweb.war file from the Tomcat_home\webapps\ directory to prevent Tomcat from redeploying the application each time the server restarts.

  6. Verify that any third-party or custom JAR files that you installed with the applications are still in-place on the application server. Restore any JAR files that were deleted when the Pega Platform redeployed.
