**Note**  
If you are an existing CRM connector user, refer to [Upgrading AWS Partner CRM connector to the new data model](connector-upgrade-plan.md).

1. Sign in to your Salesforce organization as a system administrator.

1. Choose **Setup**, **Custom settings**, **AWS Partner CRM connector settings**, and update version to **2**.

1. Choose the **ACE Mapping** tab.

1. For **Opportunity**, map it to the **ACE opportunity** custom object.

1. Choose **Auto Map ACE object**.
**Note**  
If you want to upgrade to the new version of the CRM connector that want to use the custom ACE opportunity and ACE lead objects from the connector for sandbox testing, we recommend manually deleting any available records from the `Field Mappings` and `Field Mapping Details` objects from the database before using the Auto Map ACE object feature. You only need to do this once.

1. Review field mappings and field mapping values for picklist and multipicklist.

1. Activate schedules for opportunities and leads.

1. Review the ACE Sync Logs for synchronization errors and make any required corrections.

1. Review the synced opportunities and leads to ensure the data transformation is accurate. Alternatively, review the opportunities and leads in ACE to ensure that the new data model changes have been accurately captured.
