**EKS 1.30+ STORAGE CLASS**
Starting with EKS 1.30 (AWS), support for the default annotation on the storage class has been removed. For Harness to work, update your overrides to include the `storageClassName` (gp2, gp3, etc.):
```yaml
global:
storageClass: "gp3"
storageClassName: "gp3"
```
{% endhint %}

### Terms of support
The support policy is 12 months of full support, followed by 6 months of limited support for critical security fixes only.
Harness Self-Managed Enterprise Edition does not introduce changes that break compatibility with supported versions of Kubernetes. For example, Self-Managed Enterprise Edition does not use features from Kubernetes version n that do not work in Kubernetes version n-2.
Installation and upgrade preflight checks provide warnings when you use unsupported Kubernetes versions.
In cases where you encounter a problem related to an incompatibility issue, you must upgrade your cluster. Harness does not issue a patch to accommodate the use of unsupported Kubernetes versions.
