  • Your server.xml file if you are using SSL and your current .jks certificate - this will be good as you are still on the same server
  • Download the latest install image (.iso) which is available on It includes all maintenance through cumulative build 179 and only maintenance greater than build 179 should be applied on it. It includes Tomcat 8.5.4 when doing a full install.
