# Add and Enable the OMStdBundleActivationBackCompatibility Custom Setting

Before upgrading to Order Management 109.0.3 or later, you must add and enable a custom setting that allows for backward compatibility with older versions. You only need to do this once. The next time you upgrade, you won't have to do this step.

To add and enable the `OMStdBundleActivationBackCompatibility` custom setting, follow these steps:

1. Click the **Setup** button at the top right of your org. If you're already in Setup, then you can skip this step.
    
    ![An image of the Setup button.](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-ind-order_management-264-0-0-production-enus/c2040b01-aade-4ba7-8a7d-d7cd745d5c8c/order_management/images/om-setup_btn_setup_sel.png)
2. In the Quick Find box, type Custom Settings, then click **Custom Settings**.
3. Find **XOMSetup**, and click the **Manage** link next to it. If you don't see XOMSetup, then click the **X** from among the letters at the top of the screen to filter out most of the options.
    
    ![The Custom Settings screen, with arrows pointing to the X navigation aid and the XOMSetup list item.](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-ind-order_management-264-0-0-production-enus/c2040b01-aade-4ba7-8a7d-d7cd745d5c8c/order_management/images/ompl_xom_setup.png)
4. Click the **New** button at the top of the list.
    
    ![The XOMSetup page, with the New button highlighted.](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-ind-order_management-264-0-0-production-enus/c2040b01-aade-4ba7-8a7d-d7cd745d5c8c/order_management/images/om_new_xomsetup_btn.png)
5. Enter the following information in the fields:
    
    - In both the **Name** and **Key** fields, type or paste `OMStdBundleActivationBackCompatibility`
    - In the **Value** field, type or paste `true`
6. Click **Save**.

You've added and enabled the custom setting.
