How can I upgrade a computer to 12.10 beta via Landscape?

I have Canonical Landscape managing a couple of computers.

I want to upgrade one of them to Ubuntu 12.10 beta. I don't have access to the computer in question unfortunately (it's 400km away).

I know that you're not meant to upgrade the distro version without being prepared for a non-booting system etc, but I'd still like to know if it's possible to do with Landscape, and how.
