How would I perform rolling updates to a socket.io server?

I'm currently running a load balanced socket.io node server (nginx -> socket.io x2 -> socket.io adapter (redis)) and want to update it without dropping the connections already active. The app I'm running has to keep connections active at all times of the day. I know I need to somehow move connections from one instance to another and update the instance once all connections have been transferred, but is there a peice of software or library that can handle that automatically?
