A computer can report to several different domain managers. Roaming functionality avoids duplicate entries on the enterprise manager when a computer moves between domains that are linked to the same enterprise manager.
Computers that report to a different domain will have their information (that is, delivered software, inventory attributes, and so on) moved to their new domain manager.
The computer will be deleted from the domain that it has roamed from. By default, this task is done by software delivery functionality (if installed). If software delivery functionality is not installed or configured to not preserve job history, removing the computer is done by the replication job.
Example: A Roaming Computer
Domain managers A and B are both linked to the same enterprise manager. A computer X registers to domain manager A and gets replicated to the enterprise manager. Then computer X registers to domain manager B.
Before domain manager B replicates computer X to the enterprise manager, it checks if a computer with the same UUID (that is, CA Technologies-specific UUID or hostuuid) already exists on the enterprise. It finds computer X from domain A and knows now that this computer X has roamed from domain manager A to domain manager B. The “domain A/computer X” account is deleted on the enterprise manager by the domain manager B replication and a roaming notification is stored in the enterprise manager's database. The “domain B/computer X” account is replicated to the enterprise manager. Before domain manager A replicates changes or new computers, it checks if there are any roaming notifications. It will find the one for computer X and delete it on domain manager A. (If there is a software delivery agent installed on the roaming computer, it is not deleted immediately.)
The computer X has now successfully roamed and now only exists as “domain B/computer X” in the enterprise manager's environment.
