## Summary - Document the two intermediate operating modes in a ZooKeeper-to-KRaft migration. - Explain why hybrid mode should be kept only for the broker restart window. - Describe dual-write mode as a temporary validation phase for client traffic and broker health. - Make the irreversible nature of migration finalization explicit. ## Why [KAFKA-19622](https://issues.apache.org/jira/browse/KAFKA-19622) asks for the operational limitations and risks of KRaft dual-write mode. The migration documentation currently links to the 3.9 procedure without explaining the risk distinction between hybrid and dual-write mode or what operators should verify before finalization. This change is documentation-only and does not alter the migration protocol or runtime behavior. ## Validation - `./gradlew :core:siteDocsTar --no-build-cache` - `git diff --check` The generated site-docs archive was inspected to verify that `operations/kraft.md` contains the new migration guidance.
