# Set the Omnistudio Designers to Use the Standard Data Model

As part of the migration from managed package runtime to Omnistudio standard runtime, execute an Apex class to set the Omnistudio designers to use the standard data model instead of the custom data model.

Before you begin, review the phases of the migration process to Omnistudio standard runtime. See [Migrate Omnistudio Components from Vlocity Industries Managed Packages and Custom Data Model to Omnistudio Standard Runtime](https://help.salesforce.com/s/articleView?id=xcloud.os_migrate_omnistudio_custom_objects_to_standard_objects.htm&release=264.0.0&type=5 "The Omnistudio migration process migrates components such as Flexcards, Omniscripts, Data Mappers, Integration Procedures, Omni Global Auto Numbers, Apex classes, FlexiPages, Experience Cloud site pages, Lightning web components (LWCs), and custom labels from the Vlocity Industries managed package runtime (custom data model) to the Omnistudio standard runtime (standard data model). Moving to the Omnistudio standard runtime involves migrating components from the custom data model used in Vlocity Industries managed packages to the standard data model. The Vlocity Industries managed packages include Insurance (INS), Communications, Media, and Energy (CME), and Public Sector (PS). The migration is performed using the Omnistudio Migration Assistant, which automates and guides you through the process for a smooth transition.").

1. Log in to your migration sandbox.
2. Click Setup and select **Developer Console**.
3. Execute this code.
    
    ```
    // Switch Package to use Standard Objects
    <namespace>.OmniStudioPostInstallClass.useStandardDataModel();
    ```

Example

```
vlocity_ins.OmniStudioPostInstallClass.useStandardDataModel();
```
