# Enable a module for a database













Modules add additional functionality to Redis databases for specific use cases. You can enable modules when you create a database.

## Prerequisites

- [Installed the module on the cluster](http://redis.io/docs/latest/operate/oss_and_stack/stack-with-enterprise/install/add-module-to-cluster)
- [Upgraded the module](http://redis.io/docs/latest/operate/oss_and_stack/stack-with-enterprise/install/upgrade-module) to the latest version

## Create a database with a module


You can only add modules to a database when you first create it. You cannot add modules to an existing database.


In the Redis Enterprise Cluster Manager UI, follow these steps to add modules to a database:

1. From the **Databases** screen, select **Quick database** or **Create database**.

1. In the **Capabilities** section, select one or more capabilities:

    

    
You cannot use RediSearch 1.x and RediSearch 2.x in the same database.
    

1. To use custom configuration for capabilities:

    1. Select **Parameters**.
    
    1. Enter the [configuration options](#module-configuration-options).
    
    1. Select **Done**.

1. Configure additional database settings.

    
Depending on the [features supported by an enabled module](http://redis.io/docs/latest/operate/oss_and_stack/stack-with-enterprise/enterprise-capabilities#module-feature-support), certain database configuration fields may not be available.
    

1. Select **Create**.
