 * **KOTS Auto-GitOps workflow not supported**: Embedded Cluster does not support the KOTS Auto-GitOps workflow. If an end-user is interested in GitOps, consider the Helm install method instead. For more information, see [Install with Helm](/vendor/install-with-helm).
 
-* **Downgrading Embedded Cluster or Kubernetes not supported**: Downgrading the versions of Embedded Cluster or Kubernetes that are installed in the cluster is not supported. However, the Admin Console does not prevent end-users from attempting to downgrade Emebdded Cluster or Kubernetes. To avoid issues in customer installations that could be caused by downgrading, do not promote new application releases with Embedded Cluster or Kubernetes versions that are earlier than the versions used by the previous release.
+* **Downgrading Embedded Cluster or Kubernetes not supported**: Embedded Cluster does not support downgrading the version of Embedded Cluster or Kubernetes. Only promote new releases that use the same or later versions of Embedded Cluster and Kubernetes.
 
-* **Upgrading by more than one Kubernetes version at a time not supported**: Kubernetes does not support upgrading by more than one minor version at a time. However, the Admin Console does not prevent end-users from attempting to upgrade to a release that specifies a Kubernetes version more than one minor version later than what is currently installed. To avoid issues that could be caused by skipping a minor version of Kubernetes, Replicated recommends that you select **Prevent this release from being skipped during upgrades** when you promote a new application release that increases the Kubernetes version. For more information about required releases, see [Release Properties](/vendor/releases-about#release-properties) in _About Channels and Releases_.
+* **Upgrading by more than one Kubernetes version at a time not supported**: Kubernetes does not support upgrading by more than one minor version at a time. To upgrade Kubernetes by more than one minor version, promote multiple releases, incrementing the version of Kubernetes by one minor version in each release.  
 
 * **Templating not supported in Embedded Cluster Config**: The [Embedded Cluster Config](/reference/embedded-config) resource does not support the use of Go template functions, including [Replicated template functions](/reference/template-functions-about). This only applies to the Embedded Cluster Config. You can still use template functions in the rest of your release as usual.
