After that date, community support for the version ends and clusters not enrolled in long-term support enter platform support, which covers AKS and Azure platform issues only. - Effective date: Nov 2026 (month precision: the vendor gives no day) - Cloud: [Azure](https://eolwatch.dev/cloud/azure.md) - Service: [Azure Kubernetes Service](https://eolwatch.dev/services/azure/aks.md) - Type: End of support - Category: [Kubernetes](https://eolwatch.dev/categories/kubernetes.md) - Affected versions: 1.34 - Replacement: Not stated by vendor - Announced: Not stated by vendor - Official source: [learn.microsoft.com](https://learn.microsoft.com/azure/aks/supported-kubernetes-versions) - Last checked: 12 Nov 2026 ## What breaks After the end of life date, community support for Kubernetes 1.34 ends. Clusters not enrolled in long-term support enter platform support. - Platform support covers AKS and Azure platform issues only, not Kubernetes functionality and components. New clusters cannot be created during the platform support period. - There is a 60-day platform support grace period after the published end of life date to upgrade to a supported minor version. For the initial rollout, the grace period is the window through May 31, 2027. - After the grace period, the cluster is eligible for a platform-initiated upgrade to the lowest supported community minor version. No such upgrade starts before June 1, 2027. Platform-initiated upgrades apply to AKS in the Azure public cloud; availability in Azure Government and Azure operated by 21Vianet is announced separately. - A platform-initiated upgrade does not follow the maintenance window, does not stop for deprecated API usage and can override a Pod Disruption Budget. Its month in the release calendar is a planning estimate, not an exact date. - Regional version removal can happen at a different time from the published date. ## Who is affected ### Affected versions - `1.34` ### Matching resource types - `microsoft.containerservice/managedclusters` - `azurerm_kubernetes_cluster` ### Fields the check reads - `k8sversion` - `kubernetes_version` - `support_plan` ### Detected by the estate check from - Azure Resource Graph export (CSV or JSON) - Terraform state or plan (JSON) - ARM template ## What to do 1. List the versions AKS offers for the cluster with `az aks get-upgrades --resource-group --name --output table`. 2. While the cluster is a supported non-LTS cluster, upgrade one minor version at a time. Minor versions cannot be skipped. 3. Upgrade the control plane and all node pools with `az aks upgrade`, as described in [Upgrade an AKS cluster control plane](https://learn.microsoft.com/en-us/azure/aks/upgrade-aks-control-plane). 4. If the cluster is already on an unsupported version, use the oldest supported GA target that AKS offers and perform a full-cluster upgrade. Control-plane-only upgrades are not supported for this path. The version-skipping table in [Supported Kubernetes versions in Azure Kubernetes Service (AKS)](https://learn.microsoft.com/en-us/azure/aks/supported-kubernetes-versions) labels this an unsupported recovery path: AKS allows the upgrade to proceed, but it is not supported and might carry risks. The platform support table on the same page lists upgrades from an N-3 version to a supported version as supported. 5. If no target is available for an unsupported cluster, create a new cluster with a supported version and migrate the workloads. 6. To get extended support for the version instead, enable [long-term support](https://learn.microsoft.com/en-us/azure/aks/long-term-support). This requires moving the cluster to the Premium tier and explicitly selecting the LTS support plan. Microsoft-managed Calico is not supported in LTS. Once community support for the version has ended, LTS cannot be disabled for that version. ## Replacement Not stated by vendor. ## Sources - [Official source](https://learn.microsoft.com/azure/aks/supported-kubernetes-versions) (learn.microsoft.com, Official) - [Additional source](https://endoflife.date/azure-kubernetes-service) (endoflife.date, Via endoflife.date) Last checked against the first source in this list on 12 Nov 2026.
