# Create, Import, or Open a Configuration

**Applies to:** Lasernet Core 11

Lasernet Config Server stores Lasernet Core configurations and can deploy them to Lasernet Core environments.

You can use Lasernet Developer to add a configuration to a Config Server in two ways: you can [create a new blank configuration](/v1/docs/create-or-import-a-configuration#create-a-configuration) or you can [import an existing configuration from a file](/v1/docs/create-or-import-a-configuration#import-a-configuration).

When Lasernet Developer connects to the Config Server, you can access the configurations that you and other users have created or imported. To modify one of these configurations, [open it in Lasernet Developer](/v1/docs/create-or-import-a-configuration#open-a-configuration).

> [!NOTE]
> Note
> 
> For information about creating, importing, and opening configurations in Lasernet Core 10, see the [Lasernet Config Server and Deployment Guide](/v1/docs/lasernet-config-server-and-deployment-guide).

## Create a Configuration

To create a new configuration, follow these steps:

1. In the Windows **Start** menu, click **Lasernet Developer 11** > **Lasernet Developer 11**.
2. Select a Config Server to connect to, then click **Connect**.
3. Log in to that Config Server.
4. On the **Start** page, click **New configuration**.
5. On the **New Configuration** page:
  1. Enter a **Configuration Name**.

> [!NOTE]
> Note
> 
> Each configuration that the Config Server manages must have a unique name.
  2. Enter a meaningful **Description** for the configuration.
  3. Select a Lasernet **Environment**. This list contains the environments managed by the connected Config Server. The **Environments** list in the new configuration will contain an entry for the selected environment.

> [!NOTE]
> Note
> 
> Environments are [created](/v1/docs/create-and-configure-lasernet-core-environments) and [added to the Config Server](/v1/docs/configure-the-lasernet-config-service) as a part of the [Lasernet Core 11 installation and setup process](/v1/docs/lasernet-core-11-installation-guide).
  4. Select a **Default Regional Profile**. In the new configuration, Lasernet Developer will create a regional profile named Default that uses settings from the selected profile. You can add more regional profiles to the configuration later.

> [!NOTE]
> Note
> 
> A regional profile is a collection of number, currency, time, and date formats that together are appropriate for data originating from, or intended for, a particular locale. For example, a particular country. Regional profiles are needed because (depending on project requirements) Lasernet Core might need to interpret incoming data that is formatted in a way that is used in a particular locale. It might also need to format values in output documents in a way that is meaningful to a reader in that locale.
> 
> For more information, see [Regional Profiles](/v1/docs/regional-profiles-1).
  5. Click **OK**.

Lasernet Developer creates the configuration, adds it to the Config Server, and then [opens the configuration](/v1/docs/modify-a-configuration). The configuration’s initial state becomes revision 1 of the configuration (in Config Server).

The configuration is [added to the Config Server’s list of configurations](/v1/docs/list-the-configurations-that-the-config-server-manages).

## Import a Configuration

To import a configuration from an LNCONFIGX file, follow these steps:

1. In the Windows **Start** menu, click **Lasernet Developer 11** > **Lasernet Developer 11**.
2. Select a Config Server to connect to, then click **Connect**.
3. Log in to that Config Server.
4. On the **Start** page, click **Import configuration** (see 1 in the image below).
5. In the **Select a configuration** window, navigate to and then click the `.lnconfigx` file that you want to import, and then click **Open**.

6. If prompted, in the **Include Grab** window, click **Yes** to import the configuration and the grab files that it contains, or click **No** to import only the configuration.
7. Lasernet Developer will display an **Importing Configuration** message. After it imports the configuration, it will [open the configuration](/v1/docs/modify-a-configuration). ![The Importing configuration message displayed after selecting a Lasernet configuration to import.](https://cdn.document360.io/c831ef63-c6b3-48ee-b443-3e33644e4e2e/Images/Documentation/importing configuration.png)

> [!NOTE]
> Note
> 
> Each configuration that the Config Server manages must have a unique name. If the imported configuration has the same name as an existing configuration, you must enter a different name for the imported configuration.

> [!NOTE]
> Note
> 
> The [Lasernet Developer Guide](/v1/docs/lasernet-developer-guide) describes how to export an entire configuration as an LNCONFIGX file.

## Open a Configuration

You can open any of the configurations that are managed by the Config Server that you connect to.

When you open a configuration, it loads in Lasernet Developer, where you can [modify it](/v1/docs/modify-a-configuration).

### Open a Configuration That You Recently Opened

The configurations that you have recently opened are available from the **Recent** list on the **Start** page when you start Lasernet Developer (see 1 in the image below). To open the latest revision of one of these configurations, click it in the list.

To open the configuration you most recently opened, click **Most Recent** (2). This is equivalent to clicking the configuration that is numbered **1** in the **Recent** list.

![A number-annotated screenshot that supports instructions on how to open recently accessed configurations.](https://cdn.document360.io/c831ef63-c6b3-48ee-b443-3e33644e4e2e/Images/Documentation/recent configurations.png)

### Open the Latest Revision of a Configuration That Is Not in the Recent List

To open the latest revision of a configuration (that is not in the **Recent** list), follow these steps:

1. In the Windows **Start** menu, click **Lasernet Developer 11** > **Lasernet Developer 11**.
2. Select a Config Server to connect to, then click **Connect**.
3. Log in to that Config Server.
4. On the **Start** page, click **Open configuration**.
5. Select the configuration from the **Configurations** list, and then click **Open**.

> Use the **Search filter** box to filter the list.

> [!TIP]
> Tip
> 
> You can import a configuration from this window. Click **Import configuration** and then follow the [configuration import steps](/v1/docs/create-or-import-a-configuration#import-a-configuration) (from the “In the **Select a configuration** window” step onwards).

### Open a Past Revision of a Configuration

To open a past revision of a particular configuration, follow these steps:

1. In the Windows **Start** menu, click **Lasernet Developer 11** > **Lasernet Developer 11**.
2. Select a Config Server to connect to, then click **Connect**.
3. Log in to that Config Server.
4. On the **Start** page, click **Open configuration**.
5. Select the configuration in the **Configurations** list.
6. Below the **Configurations** list, click **Open Revision**.
7. In the **Revisions** list, select the revision that you want to open, and then click **OK**.

![The Revisions list when opening a configuration in Lasernet Developer.](https://cdn.document360.io/c831ef63-c6b3-48ee-b443-3e33644e4e2e/Images/Documentation/revision list.png)

Lasernet Developer will open the configuration. The text in the Lasernet Developer window’s title bar indicates that you are viewing a past revision of the configuration. For example: **Lasernet Configuration (Revision 1) - Lasernet Developer 11**.

After you open the selected revision in Lasernet Developer, you can validate the configuration and view its history there, and you can export individual objects (such as modules) from it. However, you cannot commit or deploy that revision of the configuration.

If your Lasernet Core permissions grant you restricted user rights in Lasernet Developer, you can open an old revision of a configuration but most objects will be in read-only mode.
