EKS Upgrade Readiness

Assess and plan Amazon EKS cluster upgrades with comprehensive pre-upgrade validation aligned with the EKS Best Practices Guide.

When to Use

Activate this skill when the user asks to:

• Check if an EKS cluster is ready to upgrade
• Plan an EKS version upgrade (control plane, node groups, or both)
• Identify deprecated Kubernetes APIs before upgrading
• Validate addon compatibility with a target version
• Assess node group upgrade strategy and capacity requirements
• Review Pod Disruption Budgets or topology spread for upgrade safety
• Understand EKS end-of-support, extended support, or auto-upgrade implications
• Evaluate Karpenter Drift or node expiry upgrade behavior
• Compare in-place vs blue-green upgrade strategies
• Create an upgrade runbook or checklist
• Detect GitOps/IaC version ownership before upgrading
