Before upgrading it's strongly recommended that you backup your DomainMOD installation directory and database. If something goes wrong during the upgrade there may be no way to recover your data, and having a backup of your installation directory and database will allow you to easily restore your previous version.
The Backup & Restore instructions can be found here.
Option #1 -- Docker Install
If you installed DomainMOD using Docker, please see our official DomainMOD container on Docker Hub for upgrade information: https://hub.docker.com/r/domainmod/domainmod
