To safely refactor a Kotlin Multiplatform codebase, you enforce strict scope control to touch only required files and implement changes behind feature flags. This ensures backward compatibility, gradual adoption, and low-risk rollouts with targeted tests.

The safest way to migrate shared Kotlin code is applying minimal, scoped changes behind feature flags with clear removal plans. You must add observability through logs and metrics around transitions to monitor the migration impact effectively.

You add observability to a Kotlin Multiplatform migration by implementing logs and metrics around transition points and decision logic. This tracks behavior shifts during the rollout while ensuring no sensitive secrets are exposed.

Yes, Kotlin Multiplatform refactoring requires feature flags for compatibility to ensure backward compatibility and gradual adoption. This allows you to maintain the old code path while safely rolling out and verifying the new behavior.

The limitation of broad rewrites in Kotlin Multiplatform projects is that they violate scope control, making refactors high-risk and difficult to review. You should instead identify the smallest change that preserves behavior to keep updates auditable.
