# Modifying a Neptune DB Cluster Using the Console
<a name="manage-console-modify"></a>

When you modify a DB instance using the AWS Management Console, you can choose to apply the changes right away by selecting **Apply Immediately**. If you choose to apply changes immediately, your new changes and any changes in the pending modifications queue are applied at once.

If you don't choose to apply changes immediately, the changes are put into the pending modifications queue. During the next maintenance window, any pending changes in the queue are applied. 

**Important**  
If any pending modifications require downtime, choosing to apply changes immediately can cause unexpected downtime for the DB instance in question. There is no downtime for the other DB instances in the DB cluster. 

**Note**  
When you modify a DB cluster in Neptune, the **Apply Immediately** setting only affects changes to the **DB cluster identifier**, **IAM DB authentication**. All other modifications are applied immediately, regardless of the value of the **Apply Immediately** setting.

**To modify a DB cluster using the console**

1. Sign in to the AWS Management Console, and open the Amazon Neptune console at [https://console.aws.amazon.com/neptune/home](https://console.aws.amazon.com/neptune/home).

1. In the navigation pane, choose **Clusters**, and then choose the DB cluster that you want to modify. 

1. Choose **Actions**, and then choose **Modify cluster**. The **Modify DB cluster** page appears.

1. Change any of the settings that you want.
**Note**  
 On the console, some instance level changes only apply to the current DB instance, whereas others apply to the entire DB cluster. To change a setting that modifies the entire DB cluster at the instance level on the console, follow the instructions in [Modifying a DB Instance in a DB Cluster](#manage-console-modify-instance).

1. When all the changes are as you want them, choose **Continue** and check the summary. 

1. To apply the changes immediately, select **Apply immediately**.

1. On the confirmation page, review your changes. If they are correct, choose **Modify cluster** to save your changes. 

   To edit your changes, choose **Back**, or to cancel your changes, choose **Cancel**.
