blue-green-deployment

My understanding of a canary release is that it's a partial release to a subset of production nodes with sticky sessions turned on. That way you can control and minimize the number of users/customers that get impacted if you end up releasing a bad bug. My understanding of a blue/green release is that you have 2 mirrored production environments ("blue" and "green"), and you push changes out to all the nodes of either blue or green at once, and then use networking magic to control which environment users are routed to via DNS. So, before I begin, if anything I have said so far is incorrect,

I'm currently building an application using the ReliableActors framework on Azure ServiceFabric. As we scale up, I'm looking at doing blue/green deployments. I can see how to do this using a stateless system. Is there's a way to do this using statefull actors? Service Fabric is all about rolling upgrades, rather than deployment swaps, like a VIP swap. Both stateless and stateful services are upgraded the same way, but there are a few additional nuances to stateful that I'll mention later. By rolling upgrades, I mean upgrades to an application are done in place, one upgrade domain at a time, so
