The Problem

Technology migrations — framework upgrades, monolith decomposition, language rewrites — are the highest-risk, lowest-visibility projects in engineering. Teams start without a complete map and discover unknowns mid-flight.

​
What It Does

Covers migration strategy through traffic switch:
  • Full migration map of impacted components
  • Behavioral parity test suite to prove equivalence
  • Feature-flag-based cutover plan
  • Rollback specification

​
Try It

activate nablr
Set agent to migration_planner. Create a migration plan for [what you're migrating]
Example — framework upgrade: 
Set agent to migration_planner. Plan migration from Flask to FastAPI. Entry point is src/app.py
Parity validation after implementation: 
Set agent to parity_tester. Verify behavioral equivalence between old and new implementation
Cutover: 
Set agent to cutover_engineer. Execute feature-flag cutover with rollback plan

​
Expected Output

  • Migration map — full inventory of impacted components
  • Parity test suite — behavioral equivalence proofs
  • Cutover plan with feature flags and traffic-switch sequence
  • Rollback specification

​
Who This Is For

  • Engineering teams mid-migration with no clear exit
  • Platform modernization programs
  • Consulting firms executing technology transitions for clients
Run the parity test suite before any traffic switch. MigrationPilot blocks cutover if equivalence is unproven.
