To install the new Tomcat version included on the .NET UI media, launch the deployment script and use the Tomcat installation menu option. You can choose to install Tomcat in the same directory as an existing Tomcat installation, or in a new directory. If you choose to install the new version in an existing Tomcat installation directory and the deployment tools detect the Tomcat versions are compatible, you can optionally merge the existing Tomcat configuration files with the new Tomcat version.

Find your current Tomcat version by reviewing the release notes in the Tomcat root directory.
