Atomically? What if your DDL times out?
What you describe is, in my experience, extremely standard process for rolling out breaking changes (you do of course remove the switch and old version support after everything is rolled out).

Effectively yes, during a defined outage period (don't ask, this is finance), on any error anywhere in the platform during rollout, the entire platform would be reset to its prior state. > What you describe is, in my experience, extremely standard process for rolling out breaking changes But entirely unnecessary here. There was no requirement for a single version of the microservice to be able to address multiple versions of either dependency. It was a net negative to have that support, added significantly to the software complexity and the raw LoC.
