OpenBSD Upgrade Guide: 6.1 to 6.2


[FAQ Index] | [6.0 -> 6.1]

Upgrades are only supported from one release to the release immediately following it. Read through and understand this process before attempting it. For critical or physically remote machines, test it on an identical, local system first.
Start by performing the pre-upgrade steps. Next, boot from the install kernel, bsd.rd: use bootable install media, or place the 6.2 version of bsd.rd in the root of your filesystem and instruct the boot loader to boot this kernel. Once this kernel is booted, choose the (U)pgrade option and follow the prompts. Apply the configuration changes and finish up by upgrading the packages: pkg_add -u.

Alternatively, you can use the manual upgrade process.

You may wish to check the errata page or upgrade to the stable branch to get any post-release fixes.


Before rebooting into the install kernel

Configuration and syntax changes

Special packages


Upgrade without the install kernel

This is NOT the recommended process. Use the install kernel method if at all possible!

Sometimes, you need to do an upgrade of a machine for which the normal upgrade process is not possible. The most common case is a machine in a remote location and there is no easy access to the system console.
