Transition Planning

Migration Strategy

Detailed procedures for transitioning cryptographic systems to quantum-resistant algorithms while maintaining operational continuity and backward compatibility.

Re-encryption of Stored Data

Incrementally decrypt data protected with classical algorithms and re-encrypt using hybrid encryption scheme during off-peak hours.

Complexity:High
Risk:Medium
Large datasets at rest

Key Migration (Re-wrapping)

Re-wrap existing DEKs with new hybrid KEKs. Bulk data remains untouched while key protection is upgraded to quantum-resistant standard.

Complexity:Medium
Risk:Low
Systems with key hierarchy

Gateway Intermediaries

Deploy proxy gateways that terminate legacy protocols and establish PQC-secured connections, acting as cryptographic translators.

Complexity:Medium
Risk:Low
Legacy systems that cannot be upgraded
