Ah sorry - that was an unintended side-effect of re-upping the original submission. I must have done some of the steps in the wrong order.

You mean you don’t have a distributed merge post microservice that emits post migration events, which are then consumed by a post owner conversion service using your existing event-driven architecture to facilitate seamless data synchronization and user notification processes??? That is not very hacker news of you from the guy who owns hacker news.

I know you're joking, but I actually think complexity like that (when mostly unnecessary) is the least hackery thing in the world. Simple and effective gives me a hacker buzz
