Before upgrading it's strongly recommended that you make a backup of 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 installation.

Option #1
If you installed DomainMOD by downloading the .ZIP file, visit the following URL to download the most up-to-date version: https://domainmod.org/download/

Once the download completes, upload and unpack the new archive overtop of where you installed the previous version (or unpack it and then upload it, whichever you prefer).

Option #2
If you installed DomainMOD using git right from your web server, just run the following command from within your installation directory to upgrade:

git pull

Option #3
If you installed DomainMOD using Softaculous you're just a few clicks away from upgrading to the newest version. Please see the upgrade instructions on the Softaculous Wiki: https://www.softaculous.com/docs/How_to_upgrade_installations
