Use direct connect.5/1/07: (submitted by Eric Peng, inc#564342) Customer 479 reports work-around:Start with a clean database and using AC9.2 to copy over the data from the old database (which requires a direct connect) to the new database. They are then able to make new 3-tier connections in AC9.2 to SDE 9.2 sp2. Can someone in dev verify if this works?
