Backward Compatibility and Coexistence Model Template
Documenting how old and new versions of systems, APIs, and data formats coexist during transitions
The Backward Compatibility and Coexistence Model template provides a structured approach to documenting how old and new versions of systems, APIs, and data formats coexist during transitions.
Template Sections
This template includes 7 sections.
Coexistence Overview
Describe the coexistence requirements, the systems involved, and the expected duration of the transition
Coexistence Architecture Diagram
Diagram section
Version Coexistence Strategy
Document how multiple API or service versions are served concurrently and the routing logic
Backward Compatibility Principles
State the rules for what constitutes a breaking vs non-breaking change
Coexistence Constraints
Document constraints on how long old versions must be supported and the maximum concurrent versions allowed
Consumer Migration Steps
Document the steps consumers follow to migrate from old to new versions
Compatibility Risks
Document risks of version drift, data inconsistency between versions, and consumer migration delays
