The article describes the process of upgrading a NetBSD system from version 11.0 to 11.1 using the `sysupgrade(8)` method, which is suitable for minor version updates. The upgrade involves installing the `sysupgrade` package and running it to download and unpack the necessary kernel and sets, followed by a review and merge of new configuration changes. The author encountered a single issue with a postinstall check, which was resolved by wiping the legacy cache and rehasing certificates using `certctl(8)`, after which the system was successfully upgraded and rebooted to run the new version.
