Final answer:
To manage multiple versions of an entitlement process, versioning must be enabled in the CRM system, providing tracking and control over changes.
Step-by-step explanation:
To create and maintain multiple versions of an entitlement process in a Customer Relationship Management (CRM) system, versioning must be enabled. This feature allows for the tracking of changes, the ability to revert to previous versions, and ensures that the integrity of the entitlement process is maintained over time within the system. When versioning is enabled, it offers a historical view and control over sequential changes made to the entitlement processes, which can be critical for businesses in managing their service agreements and customer support operations effectively.
