Simplifying upgrades on the Windows platform is one of the main reasons I created an alternative Windows installer. Latest version here: https://github.com/Bill-Stewart/ApacheTomcatSetup/releases Documentation is here: https://github.com/Bill-Stewart/ApacheTomcatSetup Basically the steps would be: 1. Back up/document your 8.x configuration. 2. If you used Apache's Windows installer, uninstall it (unfortunately this removes the service and service configuration info). 3. Install the latest Tomcat version using the alternative installer, and configure Tomcat as needed. In the future, upgrades using the alternative installer are pretty simple: 1. Update the timestamps of the config files you don't want the installer to overwrite. 2. Download and run the latest version of the alternative installer to perform the upgrade. The installer automatically stops the service, upgrades the files, and restarts the service. All service configuration information is preserved. Of course, I would strongly recommend testing all of the above in a test environment first. Bill
