Post-Quantum Migration Planning

Comparison scope

One-step replacement models assume stable interoperability and immediate production readiness. Staged planning models require inventory, pilot and canary controls, and periodic standards review.

Evidence to review

PQ rollout runbook • Post-quantum migration hub • Claim C-009 evidence mapping

Decision guidance

• Use staged planning when workload heterogeneity or interoperability risk is non-trivial.
• Require monthly monitoring, quarterly review, and event-triggered reassessment before broad migration promotion.
• Document owner accountability and validation dates for every high-priority migration claim.

Planning outputs to leave with

• An inventory of cryptographic touchpoints, owners, and rollout cohorts.
• Pilot, canary, promotion, and rollback criteria for each migration stage.
• An explicit link between planning assumptions and the runbook that will execute them.

Axis is the primary landing page for operating the control-plane side of these decisions.
