Important prerequisite

To use the Open Hub Extract Stage you must first install SAP BW's Open Hub service. The Open Hub Extract stage can only be used with SAP BW installations equal to or greater than version 3.5.

IMPORTANT! To upgrade from the Extract stage to the Open Hub Extract stage you will need to update the InfoSphere® DataStage® Connection parameters to point to your 3.5 server (see in step 4 on page 9-20), and configure your server with IDENTICAL InfoSpokes and Process Chains that were used on your legacy server.
