First, check to see if you need to upgrade your OS. To find our your operating system version, type: `uname -r`. If it says `7.0`, you need to upgrade. If it says `7.1`, or `7.1-beta` you are on the most recent OS version.

Before you begin, make sure to back up any files. Use [dump](Openbsd/dump) and [restore](/Openbsd/restore) or [[rsync](/openrsync/usage).

## 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](Openbsd/cu) for [VMM](/VPS/intro) or in VNC for [[BuyVM](/Openbsd/buyvm).

Once installation begins, you will need serial console access to view

progress. If you're on OpenBSD's VMM, login to the host and use

`vmctl console`:

    host$ vmctl console username

After installation completes, you should be able to login using ssh:

    Welcome to OpenBSD: The proactively secure Unix-like operating system.
    Please use the sendbug(1) utility to report bugs in the system.
    Before reporting a bug, please try to reproduce it with the latest
    version of the code.  With bug reports, please try to ensure that
    enough information to reproduce the problem is enclosed, and if a
    known fix for it exists, include that as well.
    $ 


To check if installation succeeded:

    $ uname -a
    OpenBSD username.host.example.com 7.1 GENERIC#443 amd64


To check if you have the proper amount of RAM and number of cores, run [top](/openbsd/top).

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 -Uu


Read and fix any error messages that you may see.

You will want to reboot after some patches:

    $ doas shutdown -r now
