TeamCity supports upgrades from any of the previous versions to later ones. All available update methods are described in detail in the documentation: https://www.jetbrains.com/help/teamcity/upgrading-teamcity-server-and-agents.html It is recommended that you test the upgrade on the test server before upgrading the production one. This may help identify compatibility of non-bundled plugins (if you use any) and any other issues.
