Before you can import data from your Desktop Management System to create configuration items within Service Desk or Asset Manager, you need to create a connection to the database. If you are using Endpoint Manager or ZENworks, then you can create the required connections using the relevant node on the Connections tree.
If you are using SCCM, then you need to create a Generic Data Source connection to the SCCM database using the Data Connections component, and then specify from which table you want to import data.
When you have created this connection and connection type, you can map the fields in your existing data sources to attributes in Service Desk or Asset Manager, and import the data using the Data Import component.
To delete or rename an existing connection, right-click the connection, then select the relevant option.
The next step is to create a connection type to select the database table from which you want to import the data, and the attributes that you want to import.
