Upgrading Excel Reports

If you are using some Excel reports that require adding some JAR files <SERVER_HOME>/lib or <SERVER_HOME>/deploy/itg.war/WEB-INF/lib, or adding some class files in <SERVER_HOME>/deploy/itg.war/WEB-INF/classes, make sure these files are backed up and re-applied to your PPM instance after the upgrade as they will be removed during PPM upgrade.
