This guide shows how to create a Pro database in an existing subscription.
- If you don't yet have a Pro subscription, see [Create a Pro database with a new subscription]({{< relref "/operate/rc/databases/create-database/create-pro-database-new" >}}).
- If you'd rather create an Essentials database, see [Create an Essentials database]({{< relref "/operate/rc/databases/create-database/create-essentials-database" >}}).
{{< /note >}}

To create a database in an already existing Pro subscription: 

1. Sign in to the [Redis Cloud console](https://cloud.redis.io).

2. Select the **New database** button.

    {{<image filename="images/rc/button-database-new.png" alt="The New Database button creates a new database." width="120px">}}

    This displays the **Create database** screen.

1. Select the type of [subscription]({{< relref "/operate/rc/subscriptions" >}}) you need. For this guide, select **Existing subscription**, and then select your existing Pro subscription from the list.

    {{<image filename="images/rc/create-database-subscription-pro-existing.png" alt="The Subscription selection panel with Pro selected and an existing subscription selected.">}}

After you select your existing subscription from the list, select **Continue** to go to the **New database** page.

You can also select your subscription from the [subscription list]({{< relref "/operate/rc/subscriptions/view-pro-subscription" >}}) and select **Create database in this subscription**.

{{<image filename="images/rc/button-add-new-to-pro.png" alt="The Create database in this subscription button." width=400px >}}

The **New database** page is divided into sections, each dedicated to a specific category of settings. The following sections provide more details.

When you've configured your new database, click the **Activate database** button to create and activate it.

## General section

The **General** section defines basic properties about your database.

The available settings vary according to your subscription plan:
