(redirected from Openbsd.Sysupgrade)
This is a quick upgrade guide for OpenBSD 7.5 using sysupgrade.
NOTE: This guide is no substitute for reading the OpenBSD FAQ. In particular, you should read the Upgrade Guide.
First, check to see if you need to upgrade your OS. To find our your operating system version, type: uname -r. If it says 7.4 or earlier, you need to upgrade. If it says 7.5, or 7.5-beta you are on the most recent OS version.
Before you begin, make sure to back up any files. Use dump and restore or rsync.
Performing the Upgrade
$ doas sysupgrade
Running sysupgrade above will automatically download the base sets and reboot the system for installation. The upgrade will begin automatically. You can view it in the serial console? for VMM or in VNC for BuyVM.
