How to manage migration of hsm1.medium CloudHSM clusters to hsm2m.medium
- AWS announced the general availability of hsm2m.medium CloudHSM clusters with advanced features compared to hsm1.medium clusters.
- hsm1.medium CloudHSM clusters will reach end-of-life on December 1, 2025, prompting migration to hsm2m.medium clusters.
- Starting April 2025, AWS will attempt to automatically migrate existing hsm1 clusters to hsm2 with limited-write mode during migration.
- Consider automatic migration prerequisites or manage migration manually using options provided based on resources and requirements.
- Backup hsm1 data and ensure compatibility with hsm2 instance type, client SDK versions, and deprecated algorithms.
- Choose between customer-triggered or customer-managed migration approaches depending on readiness and write operation needs.
- For customer-managed migration, create an hsm2 cluster from hsm1 backup, configure for high availability, reconfigure client SDKs, monitor the application, and execute rollback if needed.
- Implement blue/green deployment for high availability during migration using load balancer or CloudHSM multi-cluster configuration.
- Address different use cases for read-only and create/delete operations during migration, ensuring data synchronization between blue and green clusters.
- Rollback strategies involve reconfiguring applications, replicating keys, and syncing between hsm1 and hsm2 clusters based on the migration stage and key creation.
