IMPORTANT NOTE: After upgrading to a newer version users might need to clear the browser's cache in order to avoid compatibility problems with the older version.
In order to upgrade the system to the latest version all you have to do is to follow these simple steps:
Download the latest version from the link found on the bottom of Dashboard while logged in with administrator rights and extract the new RationalPlan.war file to a desired location.
Delete the old RationalPlan.war and RationalPlan folder from Tomcat's webappsfolder and copy the new RationalPlan.war file.
Restart Tomcat.
