I've come close to that many, many times with zero downtime. It does take planning, more than many folks would think. But it can be done as long as you think it through.

I've never done anything close to that scale of migration, but I also can't really imagine taking an approach that feels like a huge migration.

I feel like I would try to strangle the old app (putting proxies in front and redirecting endpoints as they're rewritten) rather than swapping it out wholesale.

At that point I don't know if it really counts as a migration as much as just development.

Any thoughts on that approach? Is that what you have done, or was it a more holistic swap over?

That isn't a data migration, that's a release.
