# Edit an Amazon MQ for ActiveMQ configuration revision
<a name="edit-current-configuration-console"></a>

You may want to edit a configuration revision after applying it to your broker. Use the following instructions to edit a configuration revision.

1. Sign in to the [Amazon MQ console](https://console.aws.amazon.com/amazon-mq/).

1. From the broker list, select your broker (for example, **MyBroker**) and then choose **Edit**.

1. On the ***MyBroker*** page, choose **Edit**.

1. On the **Edit *MyBroker*** page, in the **Configuration** section, select a **Configuration** and a **Revision** and then choose **Edit**.
**Note**  
Unless you select a configuration when you create a broker, the first configuration revision is always created for you when Amazon MQ creates the broker.

   On the ***MyBroker*** page, the broker engine type and version that the configuration uses (for example, **Apache ActiveMQ 5.15.8**) are displayed.

1. On the **Configuration details** tab, the configuration revision number, description, and broker configuration in XML format are displayed.
**Note**  
Editing the current configuration creates a new configuration revision.

1. Choose **Edit configuration** and make changes to the XML configuration.

1. Choose **Save**.

   The **Save revision** dialog box is displayed.

1. (Optional) Type `A description of the changes in this revision`.

1. Choose **Save**.

   The new revision of the configuration is saved.
**Important**  
The Amazon MQ console automatically sanitizes invalid and prohibited configuration parameters according to a schema. For more information and a full list of permitted XML parameters, see [Amazon MQ for ActiveMQ broker configurations](amazon-mq-broker-configuration-parameters.md).
