PHASE 05 — RETIRE THE OLD

MIGRATION WITHOUT RETIREMENT ISN'T MIGRATION

Running hybrid indefinitely means paying twice and trusting twice. The value is only unlocked when you decommission the classical primitive — safely, provably, and with audit evidence.

PROVE IT, THEN TURN IT OFF

• 01

  Attestation gates

  Per-endpoint attestation that PQC is active before classical is disabled. No silent fallback.

• 02

  Canary decommissioning

  Disable classical in one tier, measure impact, roll forward. Roll back is always one toggle away.

• 03

  Regulator-ready evidence

  Immutable logs showing the when, where, and how of every algorithm transition. Sign-offs captured.

• 04

  Quarterly board report

  PQC posture, outstanding classical exposure, partner catch-up status — in a format your board reads.
