The OpenBSD project unveiled version 7.9 of their operating system on May 19, 2026, marking their 60th release. This post provides a guide on upgrading from OpenBSD 7.8 to 7.9, based on the official documentation. The recommended method for upgrading is sysupgrade, a system that automatically handles the upgrade process but should be run with caution as it cannot be stopped once initiated.
Prior to upgrading, it is advised to check available disk space and ensure the /usr partition has at least 1.1GB of available space. Additionally, compatibility with the new release should be verified, including updates to PostgreSQL to version 18.1. Users have the option to create backups, customize the upgrade process using a response file, or proceed with the standard upgrade.
After running sysupgrade, the system will reboot multiple times, during which the state of the upgrade will be displayed. Once the upgrade is complete, the system will reboot again, and sysmerge may be necessary to reconcile any configuration changes that could not be automated. After addressing any manual configuration changes, the system should be updated to the latest packages using pkg_add -u.
The final step is to reboot the machine, and upon login, users will notice they are now running OpenBSD 7.9.
