PQC Migration Planning

Planning comparison for one-step algorithm replacement versus staged post-quantum migration governance.

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.
