Planning a migration from AWS Outposts first-generation to second-generation

This article provides a comprehensive guide for migrating workloads from first-generation to second-generation AWS Outposts, covering benefits, architectural differences, migration tools, and a phased execution framework.

• Second-generation Outposts deliver 2x vCPU/memory/bandwidth with 40% better performance and a dedicated network rack included at no additional charge
• Key architectural changes include decoupled compute and networking, self-service local gateway configuration, and built-in automatic network failover
• Three-phase migration approach: Assess (inventory and dependency mapping), Mobilize (install agents and configure staging), and Migrate & Modernize (wave-based cutover)
• AWS Transform MGN, EBS snapshots, and S3 Replication on Outposts provide different migration paths based on data residency and downtime requirements
• Rollback strategies include Blue/Green deployment, database snapshot restore, and canary deployments for risk mitigation
• Post-migration optimization includes right-sizing instances, exploring accelerated networking, and implementing self-service routing domains

Organizations can achieve significant performance gains and operational simplification by strategically planning and executing a structured migration to second-generation Outposts.
