Unfortunately the officially documented process from Canonical is to use the update-manager tool, which is an interactive curses app if I remember correctly. I would check to see if it has a non-interactive mode. Otherwise you can do it the really old fashioned way of replacing your sources.list and apt-get dist-upgrade.

Thats fine as an opinion, but multiple people responding to a question with "don't do that" breeds an unwelcoming atmosphere. I agree it is going to be a frustrating use case, but at a minimum let's answer the question to the best of our ability first and then urge caution after that. The "How? Don't!" thing is a cliche for a reason, and I know I personally hate being on the other side of it.
