    Sorry you have to deal with this. You can stay on Azure Kubernetes Service (AKS). Here is what to change before March 2027, which AKS counts as March 31, 2027:

1. Check cluster versions. In the Azure portal, check the Kubernetes version of each cluster. Look for 1.35.
2. Remove deprecated APIs. In the portal, open Diagnose and solve problems, then Kubernetes API deprecations.
3. Upgrade before the date. Run az aks upgrade to a supported version, then set the stable auto-upgrade channel.
