To directly upgrade an existing VyOS system to a new image:
On your VyOS host (from an admin-level account):
add system image https://mirror.tuxhelp.org/vyos/iso/release/<version>/vyos-<version>-<architecture>.iso
add system image https://mirror.tuxhelp.org/vyos/iso/release/1.1.8/vyos-1.1.8-amd64.iso
Optional: If desired, give the new image a descriptive name.
Confirm your changes. The new image will become active after the next reboot.
NOTE: This mirror is hosted from the west coast of the USA. If you're geographically distant, you may be able to find a closer one. See https://wiki.vyos.net/wiki/Mirrors for the full listing.
