# View an AWS Cloud WAN core network policy change set
<a name="cloudwan-policy-version-view"></a>

View proposed changes to a policy before deploying those changes to become the new live policy.

A policy version is never implemented automatically. After creating a version of a policy, you can implement the policy version as your new **LIVE** policy.

**To view a core policy version change set**

1. Access the Network Manager console at [https://console.aws.amazon.com/networkmanager/home/](https://console.aws.amazon.com/networkmanager/home).

1. Under **Connectivity**, choose **Global Networks**.

1. On the **Global networks** page, choose the global network ID.

1. In the navigation pane, choose **Core network**, and then choose **Policy versions**.

1. In the **Policy versions section**, choose the check box that you want to see policy changes for.

1. Choose **View or apply change set**. This creates a new version of the policy. The policy version is incremented by one from the last policy version. 

1. The **Change set **page displays the **Type** of change being affected, for example, a core network segment, and the **Action** that's associated with that type, for example, adding a new segment.

1. In **New Values** and **Previous values**, choose **Details** to view the change in a JSON format.

1. In the **Compare** column, choose **Compare** to view a line-by-line comparison of the current live policy with the proposed policy change.
