Users who upgrade to InfoSphere® Information Server, Version 9.1, must be aware of the following requirement for importing metadata.
Because of extensive changes in the Microsoft SQL Server Database bridge, you cannot share existing staged imports or reimport into the same import area after you upgrade to InfoSphere Information Server, Version 9.1. Any existing import areas that were created by using the bridge are locked.
To import from the same source with the same import settings, create an import area, choose the Microsoft SQL Server Database bridge, and specify the same parameter values that you specified for the existing import area.
