Compatibility-Safe Migration Strategies

v20260905

migration

This mechanism facilitates the implementation of reversible and compatibility-safe transitions across critical system components. It is essential for managing changes in schemas, APIs, protocols, configurations, or data structures, ensuring that rollbacks are possible and the integrity of existing data is preserved throughout the migration process. Best practices include defining explicit forward and rollback paths, handling mixed-version operations, and ensuring idempotency for retries.

Overview

Migration

Map current readers, writers, data shape, compatibility window, and ownership before editing.

Define forward path and rollback path.
Preserve existing data; make destructive steps explicit and separately authorized.
Keep mixed-version operation safe where rollout can overlap.
Sequence expand, migrate, verify, then contract when applicable.
Make retries idempotent and partial failure observable.
Verify old and new paths at required transition stages.

Stop after requested stage passes; do not perform later destructive contraction implicitly.
