We did the exact thing not too long ago, but we couldn't do it using blue/green. We were able to minimize downtime quite a bit, but it was on the order of minutes, not seconds. I wrote a little bit about the process here. I spent a lot of time prepping and running the migration, so happy to share any details if it's helpful.
