To minimise down-time to a simple reboot - best not to rush these things, and there's nothing like a production system being down to cause me to rush! Thanks to Nick for the advice, it seemed to work fine. For the archives, just make REALLY sure you replace / with /altroot at every step in the upgrade instructions (I slipped a couple of times, thankfully both instances were recoverable) and I did find some minor steps e.g. running newaliases(8) that would seem to require the system being upgraded to be live and running.
