Use the administrative console whenever possible to reduce the risk to data integrity.
The import process is not subject to the same rigorous data validation performed by the administrative user interface. Although some checks are made, it is possible to create invalid connections using the connection-migration process. As the XML is complex and validation is limited, use the administrative console to create the initial XML connection instead of attempting to create an XML connection from scratch. That way, changes necessary to the exported connection's XML representation can be held to a minimum, reducing the risk of compromising data integrity.
