Don't *plan* for any downtime and don't patch! Planned downtime will be zero, actual downtime will be close to that of ha sites. People won't like this much of course. Also you should never allow application upgrades. This suggestion isn't entirely facetious by the way, may people spend huge amounts just to match single instance terminal release availability. Do nothing is a surprisingly good option here.
