Its best to uninstall before installing the new version. But you must make sure you keep copies of server.xml, web.xml, webapps, and things you've put into common/lib and common/classes so you ca restore these into the new Tomcat directories.
Don't just copy your old conf/server.xml and conf/web.xml back into the conf directory - edit the new files and put your changes into the new files. There are sometimes changes in these conf/*.xml files which you need to keep. Another point if you are using Linux and have installed RPMs - if you've added users into the tomcat4 group you should remove them from the group before uninstalling the RPM. If you don't then the tomcat4 group stays and subsequent RPM installs won't work properly. (But there isn't yet a 4.1.27 RPM - as I mentioned in my earlier e-mail). I have done this a number of times as we've progressed through most versions of tomcat since 4.0.2. Good luck.

However I can't find any "How Tos" on this topic. Do I just install the new version on top of my old one or is it a new install??? Not sure how to proceed, any advice would be appreciated.
