Migration playbook

GitHub Copilot to Amazon Q Developer migration plan

Move from GitHub Copilot to Amazon Q Developer in phases: plan, pilot, controlled rollout, and optimization. Keep rollback paths and KPI checkpoints in each phase.

Effort: mediumTimeline: 3 to 6 weeksLast reviewed: 2/13/2026

Start here

  • Expected rollout window: 3 to 6 weeks.
  • Begin with prerequisites and pilot, then use the checklist for rollout sequencing.
  • Validate results against your KPI baseline before full cutover.

Reading density

Switch between comfortable and compact spacing for long pages.

Why teams switch

  • AWS-native developer workflow: Amazon Q Developer is tightly integrated with AWS platform usage.

When staying is reasonable

  • General GitHub engineering workflows: Copilot is optimized for broad IDE plus GitHub workflow adoption.

Preconditions before migration

  • Define success KPIs for moving from GitHub Copilot to Amazon Q Developer.
  • Assign one migration owner and one rollback owner.
  • Back up critical data and export baseline workflow artifacts.

Phased rollout plan

Phase 1: Audit and plan

Week 1

Document current GitHub Copilot workflows and migration constraints.

Tasks

  • Inventory current automations, integrations, and permission models.
  • Identify top 3 workflows that must be reproduced in Amazon Q Developer.
  • Define measurable before/after baselines for cycle time and output quality.

Exit criteria

  • Scope approved by stakeholders.
  • Rollback plan and owner confirmed.

Phase 2: Pilot

Weeks 2 to 3

Validate Amazon Q Developer on one team or one workflow.

Tasks

  • Migrate one non-critical workflow from GitHub Copilot to Amazon Q Developer.
  • Track throughput, defects, and collaboration friction.
  • Collect team feedback and adjust process docs.

Exit criteria

  • Pilot workflow meets or exceeds baseline KPIs.
  • No unresolved blocker for full migration.

Phase 3: Controlled rollout

Weeks 4 to 6

Expand migration in controlled waves with guardrails.

Tasks

  • Migrate remaining workflows in batches, highest impact first.
  • Monitor adoption metrics and support issues after each batch.
  • Pause rollout if quality, velocity, or reliability regresses.

Exit criteria

  • 90%+ targeted workflows migrated without critical regressions.
  • Support load remains within agreed threshold.

Phase 4: Optimization

Weeks 7+

Optimize Amazon Q Developer usage and retire legacy paths.

Tasks

  • Finalize templates, permissions, and onboarding docs.
  • Decommission unused GitHub Copilot paths to reduce duplicate maintenance.
  • Review ROI assumptions against real post-migration metrics.

Exit criteria

  • Legacy tool usage reduced to planned floor.
  • Post-migration ROI review completed with next actions.

Execution checklist

  1. Define which workflows currently depend on GitHub Copilot or Amazon Q Developer.
  2. Run both tools on one real sprint and score quality, speed, and review overhead.
  3. Choose one default team standard and document exceptions clearly.

Risk controls

  • Run dual systems for one sprint on critical workflows.
  • Document rollback triggers before each migration phase.
  • Track user adoption and issue volume weekly.
  • Delay full cutover until pilot KPIs are stable for 2 cycles.
