I guess that a hard question for user facing API: you need to support both the old and the new features during the migration.

In our case, this design principle mostly applied to our internal APIs. Particularly, we designed our internal sub components (consensus protocol, particularly) in a way we can swap it without any downtime.

Right. So it seems you did a lift and shift over two years without changing the basic API surface. That’s ok, but stability of requirements throughout a rearchitecting project is a luxury and not the norm
