EKS 1.34 upgrade guide

Plan an Amazon EKS 1.34 upgrade with lifecycle dates, support-tier cost context, route-to-target notes, deprecated API checks, add-on validation, and change evidence collection.

Lifecycle facts

  • EKS 1.34 release date: 2025-10-02.
  • Standard support ends: 2026-12-02.
  • Extended support ends: 2027-12-02.
  • Latest platform recorded in the static dataset: 1.34-eks-23.

Upgrade planning focus

  • Use EKS 1.35 or newer as the target planning line when it is available for your workloads.
  • Check deprecated Kubernetes API versions before the control plane hop and before workload rollout windows.
  • Validate managed add-ons, platform controllers, node groups, networking, storage, and observability after each hop.
  • Control-plane support tier pricing only. Worker nodes, Fargate, EBS, data transfer, IPv4, and add-on costs are not included.

Evidence to collect

  • Lifecycle source: AWS EKS Kubernetes version lifecycle.
  • Attach support-tier cost assumptions, add-on preflight output, deprecated API scan output, and post-upgrade smoke test evidence.
  • Verify every static recommendation against AWS documentation and live cluster state before production approval.
