Use connectors to import data into Service Manager
You can use System Center - Service Manager connectors to import data as configuration items from Active Directory Domain Services (AD DS), System Center Configuration Manager, System Center Orchestrator, System Center Virtual Machine Manager, and System Center Operations Manager. In addition, you can import alerts from Operations Manager, and you can configure these alerts to automatically generate incidents in Service Manager. You can also import data from comma-separated value (CSV) files into the Service Manager database.
Effects of deleting a connector on configuration items
Many of the configuration items that are found in the Service Manager database are the result of the data that is imported by using connectors. Therefore, if a connector is deleted, the configuration items that are associated with that connector will also be deleted, except where the configuration item is related to an active incident or change request. If more than one connector defines a configuration item, the configuration item will be deleted when all of the contributing connectors are deleted.
If you are creating a new connector to replace an existing connector, create the new connector first, and then synchronize the new connector before deleting the old connector.
You can use a Windows PowerShell command to remove a connector from Service Manager. For more information, see Remove-SCSMConnector.
