Phase 5: Migration & Real World
Knowing the algorithms is only half the battle. The real challenge is migration — replacing deeply embedded cryptography in production systems, often without taking anything offline. This phase covers the practical strategies, tools, and real-world context you need to actually make systems quantum-safe.
