You download the regular install image, put it on a USB stick, boot
from that and tell sysinst you want to upgrade a system ("b: Upgrade
NetBSD on a hard disk"), then point it at the root disk you usually
boot from.

This is documented e.g. here:

https://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-10/latest/amd64/INSTALL.html#Upgrading%20a%20previously-installed%20NetBSD%20System

(but you are right, docs could be improved).
