Deprecation and migration

Decision questions

  1. Does the old system still provide unique value?
  2. How many consumers? Migration cost each?
  3. Is replacement production-proven?
  4. Cost of NOT deprecating (security, maintenance)?

Compulsory vs advisory

TypeWhen
AdvisoryStable legacy, optional migration
CompulsorySecurity risk, blocks progress — need tooling + deadline

Default advisory unless risk justifies force.

Process

  1. Build replacement first
  2. Announce — status, replacement, migration guide, timeline
  3. Migrate consumers incrementally; owner migrates users when possible
  4. Remove only after zero active usage verified

Patterns

PatternUse when
StranglerGradual traffic shift
AdapterOld interface, new implementation
Feature flagPer-consumer or cohort cutover

Zombie code signals

  • No maintainer, active dependents, failing tests ignored, stale deps

Output

Deprecation notice + migration steps + removal checklist.
