Abstract: A computer-implemented system and method are provided for process control during a transfer of an entity from a transferor system to a transferee system. The method comprises, in a pre-transition state, storing data of a user in the memory comprising combined non-divested data that remain with the transferor, and to-be divested data that are a part of the entity and remain with the entity during and after the transfer. In a transitional state, the method provides full access to the user data by the transferor, provides additional limited access to the to-be divested data by the transferee, receives required new access credentials permitting the user to access the to be divested data, and partially restricts access to the to-be divested data. In a final state, the method divests the to-be divested data, making it divested data, and removes access to the divested data by the transferor.
