# Migration

> How to import and export your full CData Arc application data and settings.

The **Migration** portion of the **Advanced** page enables you to perform a full import, export, or migration of your application, including all of the global application data and settings.

![Migration section on the Advanced settings page](https://docs.arc.cdata.com/26.4/images/settings_migration.png)

Use the **Export** button to export global application data. Doing so exports your data in an ARC file (`.arc` extension). This file type stores global application data such as multiple workspaces and settings as well as users, roles, reports, and other global data.

In a similar way, you can import application data by using the **Import** button to import an ARC file.

For details about how to use the **Migration** settings to import or export your application, see [Importing and Exporting](https://docs.arc.cdata.com/26.4/self-hosted/en/getting-started/administration/importing-exporting-flows.md).

To migrate your application from the embedded database to an external database, use the [Application Database Migration](https://docs.arc.cdata.com/26.4/self-hosted/en/getting-started/administration/settings/app-db-migration.md) utility.
