First, check to see if you need to upgrade your OS. To find our your operating system version, type: `uname -a`. If it says `OpenBSD fruit.ircnow.org 6.7 GENERIC#6 amd64`, you need to upgrade. If it says `OpenBSD fruit.ircnow.org 6.8 GENERIC.MP#98 amd64`, you are on the most recent OS version.

Next, make sure to back up any files. Use [dump](Openbsd/dump) and [[restore](/Openbsd/restore).

You will want to [patch](/Openbsd/syspatch) the system:

    $ doas syspatch


Then, you'll want to run [sysmerge](/https://man.openbsd.org/sysmerge) to merge any configuration files:

    $ doas sysmerge


Then, make sure to upgrade your packages:

    $ doas pkg_add -u


Read and fix any error messages that you may see.
