Migrating Storage Gateways from Amazon Linux 2 to AL2023 After the EOL Deadline
Short summary
Amazon Linux 2 reached end of standard support on June 30, 2026, meaning any AL2-based AWS Storage Gateway appliances are now unsupported and accumulating compliance risk. Unlike normal EC2 workloads, Storage Gateway has no in-place upgrade path — you must replace the gateway instance and migrate the gateway ID and cache disk to a new AL2023 appliance. The guide covers inventory methods, migration sequencing by risk, and operational lessons for fleets of any size.
- •AL2 support ended June 30, 2026 — all AL2 Storage Gateways are now unsupported
- •No in-place upgrade exists; migration requires replacing the gateway instance while preserving the gateway ID and cache disk
- •Inventory via console, DescribeGatewayInformation API, and AWS Health Dashboard; sequence by risk starting with internet-facing and compliance-critical gateways
