Get the latest release from the tomcat website, not the Red Hat RPM and you can install it in parallel with your existing Tomcat, so you can switch back quickly if you do experience a problem related to the upgrade. You will need to migrate your server.xml file and possibly you context.xml files as well, though unlikely in the latter case. I know that a lot depends on how tightly integrated your app is with tomcat, but I made the migration with almost no difficulty years ago. Jeff
