If the upgrade fails, it may not be possible to recover your data. Take a VM snapshot or backup of your server before proceeding.

Tomcat is upgraded from version 9 to 10

Java - is upgraded to version 21 (Java 17 for AWS deployments)

PostgreSQL - is upgraded from version 13 to 16.

- Tomcat is upgraded from version 9 to 10
- Java - is upgraded to version 21 (Java 17 for AWS deployments)
- PostgreSQL - is upgraded from version 13 to 16.

Tomcat and Java are upgraded as part of the standard upgrade process. Follow the <a href="https://support.faddom.com/en/articles/9428901-upgrading-the-faddom-server">Upgrading the Faddom Server</a> guide to complete this step.

AWS deployments: Java will be upgraded to version 17 instead of 21. No additional steps are required.

PostgreSQL 13 reached End of Life in November 2025 and will no longer receive security patches. Upgrading to PostgreSQL 16 is recommended, but Faddom will continue to work on PostgreSQL 13 if you choose not to upgrade.

If you choose to upgrade, note that the process is manual and runs after the main upgrade completes. Faddom will not be accessible during this time.
