# Import a custom cluster configuration

You can configure Coherence clusters within WebLogic Server or externally in a custom configuration file. You import a custom configuration by specifying its file path location on your system.

To import a custom cluster configuration:

1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
2. In the left pane of the Console, expand Environment and select Coherence Clusters.

   The Summary of Coherence Clusters page displays the Coherence cluster configurations that have been created in this domain.

3. Click New.
4. On the Configuration: General page:
   1. Name: Provide a name for this Coherence cluster configuration.
   2. Use a Custom Cluster Configuration File: Select to configure this cluster using an external custom configuration file and click Next.
   3. File Path: Provide the file path location of configuration file. The file must be present locally on the Administration Server.
5. Click Next to select targets for the Coherence cluster or click Finish.
6. Optionally, select WebLogic Server instances or clusters on which this cluster configuration is accessible and click Finish.

   The new cluster configuration appears in the Coherence Clusters table.

7. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
   Not all changes take effect immediately—some require a restart (see Use the Change Center).
