A company wants to migrate their existing in-house order management solution to the Salesforce Order...

Salesforce Order Management is a product that allows managing orders across different channels and systems. To migrate the existing in-house order management solution to the Salesforce Order Management product, the following actions should be taken:

Configure data extensions and triggered sends in Marketing Cloud to support transactional emails for ordering scenarios. Data extensions are tables that store data in Marketing Cloud, and triggered sends are email messages that are sent automatically based on an external event. Data extensions and triggered sends can be used to store order data and send order confirmation, shipment notification, or cancellation emails to customers.

Modify the Service Cloud Connector implementation to remove potentially conflicting features with the Order Management Connector. The Service Cloud Connector is a cartridge that enables integration between B2C Commerce and Service Cloud. The Order Management Connector is a cartridge that enables integration between B2C Commerce and Salesforce Order Management. Some features of the Service Cloud Connector, such as order history or order cancellation, may conflict with the Order Management Connector, so they should be removed or disabled.

Integrate Salesforce Order Management to B2C Commerce for order history and user self service. This integration allows customers to view their order history and status, track their shipments, cancel their orders, or initiate returns on the B2C Commerce storefront. This integration also allows agents to view and manage orders in Service Cloud.

Option D is incorrect because migrating subscriber keys in Marketing Cloud to a new Order Management customer identifier is not necessary or recommended. Option E is incorrect because replacing the Service Cloud Connector with an Order Management Connector for B2C Commerce is not possible or advisable. References:
