# Transforming a RAML OData v2 API to a CSDL OData v4 API

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

Migrate from APIkit for OData v2 to OData v4 by reusing your RAML entity model: Studio converts
`odata.raml` into `odata.csdl.xml` (Common Schema Definition Language) so you can scaffold OData v4
flows from the same types. The new file lands under the `api` folder next to your existing assets.

In Studio, right-click your `odata.raml` file and select **Mule** > **Generate CSDL file**.

![\*Generate CSDL file\* option highlighted in the Mule section when right-clicking the OData file in the Package Explorer](/mulesoft/current/en-us/apikit/latest/_images/generate-csdl-file.png)

APIkit generates an `odata.csdl.xml` file in the **api** folder.
