By 2028: Determine the organization's migration goals, complete a comprehensive assessment of existing cryptographic assets and infrastructure (discover all systems that rely on cryptography), and develop a preliminary migration plan.

By 2031: Complete the migration of quantum-resistant cryptography for the highest priority and most critical assets, enable the infrastructure to support quantum-resistant cryptography, and refine and improve the migration roadmap accordingly to prepare for full migration.

By 2035: Complete the deployment of quantum-resistant cryptographic solutions for all systems, services, and products to achieve comprehensive quantum attack resistance. Although a few unpopular technologies may face migration difficulties, organizations should still strive to achieve their goals before this time point.
