I am importing lagacy data. I have imported the data using sqlBulkCopy the old data priamry key is a random number entered by the user so they are all over the place. The new tables auto generate the primary keys. I heed to link te two tables on a field containing the old primary key so that I can update the FK with the new PK. I have been looking at the BusinessLayerLinkManager but am not getting anywhere. Is that the way I should be doing this?
