Thank you both Ewen & Andrey! The general rule of upgrading brokers is clear, but it was important for me to hear what other people experienced. Ewen, I assume the broker upgrade from 0.8.1.1 to 0.8.2.2 is as safe as it could be, right? Like I can just take down a single broker, replace jars, and kick it up again seamlessly. If so I will probably give it a go unless another better version is coming.
