Yesterday our VP of tech did a vlog with Bret Fisher, and the interview was fairly wide ranging, but at this point: https://youtu.be/_i4gZDJS_9g?t=2652 he gets asked the question of how to migrate a system with 50+ microservices to Docker. He talks about dividing and conquering, not doing a big bang migration, and limiting the blast radius.
I think given our experience with the HackerNoon migration there are some good lessons here. There may have been a way to start the migration with just new articles going onto the new system and old links still working, or even just a fraction of new articles going onto the new live system until kinks were worked out. The big bang migration attempt has probably caused people to have some late nights and based on threads in this community has caused some writers a bit of consternation.
This is exactly the type of lesson that could be useful for the readership, and I’d encourage someone inside the migration to write this story and talk about how they’d do it differently if they could do it again. I personally can’t write it because I don’t have enough details on the decision process and the available migration options.
Food for thought!
Looking forward to smooth seas ahead.
