Nova has spent the last few years learning how to do live upgrades, developing technology and best practices along the way. Other projects are starting to identify upgrades as a key feature requirement. We should have a cross-project session dedicated to sharing the challenges and strategies learned over the years.
I propose a session where we provide a short background of nova's journey, identify the key challenges, and then quickly move to Q&A/discussion with people working in other projects trying to actually move the ball forward.
