Compatibility Bridge Design

Design compatibility layers to bridge old and new systems during migration.

Migration Checklist

Adapter Design

• Define adapter interfaces for changed APIs
• Implement wrappers that translate old calls to new APIs
• Ensure adapters handle edge cases from both versions
• Verify adapter performance overhead is acceptable

Abstraction Layers

• Create version-agnostic abstractions over divergent APIs
• Isolate version-specific code behind clean interfaces
• Ensure abstractions do not leak implementation details
• Validate abstraction coverage for all affected call sites
