+# Azure Kubernetes Service (AKS) node pool snapshot
 
 AKS releases a new node image weekly and every new cluster, new node pool, or upgrade cluster will always receive the latest image that can make it hard to maintain your environments consistent and to have repeatable environments.
 
 Node pool snapshots allow you to take a configuration snapshot of your node pool and then create new node pools or new clusters based of that snapshot for as long as that configuration and kubernetes version is supported. For more information on the supportability windows, see [Supported Kubernetes versions in AKS][supported-versions].
 
 The snapshot is an Azure resource that will contain the configuration information from the source node pool such as the node image version, kubernetes version, OS type, and OS SKU. You can then reference this snapshot resource and the respective values of its configuration to create any new node pool or cluster based off of it.

 ## Before you begin
 
 This article assumes that you have an existing AKS cluster. If you need an AKS cluster, see the AKS quickstart [using the Azure CLI][aks-quickstart-cli] or [using the Azure portal][aks-quickstart-portal].
 
 ### Limitations
 
 - Any node pool or cluster created from a snapshot must use a VM from the same virtual machine family as the snapshot, for example, you can't create a new N-Series node pool based of a snapshot captured from a D-Series node pool because the node images in those cases are structurally different.
-- During preview, snapshots must be created and used in the same region as the source node pool.

-### Install aks-preview CLI extension
-
-You also need the *aks-preview* Azure CLI extension version 0.5.40 or later. Install the *aks-preview* Azure CLI extension by using the [az extension add][az-extension-add] command. Or install any available updates by using the [az extension update][az-extension-update] command.
-
-```azurecli-interactive
-# Install the aks-preview extension
-az extension add --name aks-preview
-
-# Update the extension to make sure you have the latest version installed
-az extension update --name aks-preview
-```
-
-### Register the `SnapshotPreview` preview feature
-
-To use the feature, you must also enable the `SnapshotPreview` feature flag on your subscription.
-
-Register the `SnapshotPreview` feature flag by using the [az feature register][az-feature-register] command, as shown in the following example:
-
-```azurecli-interactive
-az feature register --namespace "Microsoft.ContainerService" --name "SnapshotPreview"
-```
-
-It takes a few minutes for the status to show *Registered*. Verify the registration status by using the [az feature list][az-feature-list] command:
-
-```azurecli-interactive
-az feature list -o table --query "[?contains(name, 'Microsoft.ContainerService/SnapshotPreview')].{Name:name,State:properties.state}"
-```
-
-When ready, refresh the registration of the *Microsoft.ContainerService* resource provider by using the [az provider register][az-provider-register] command:
-
-```azurecli-interactive
-az provider register --namespace Microsoft.ContainerService
-```
+- Snapshots must be created and used in the same region as the source node pool.
