Pachetele SSIS au "din fabricatie" (---> template-ul "Integration services project" din VS) format "dtsx". SSIS ofera suport pentru pachetele DTS - exista de exemplu task-ul "Execute DTS 2000 package" - pachetul DTS poate fi executat, insa nu poate fi modificat cu designerul din VS. Nu poti sa "faci" un pachet DTS 2000 folosind BI Studio. Dar, dupa cum poti citi in BOL,

"You can edit DTS packages, even when the SQL Server 2000 tools are not present, by using an updated version of the DTS Designer that is available for download. You cannot edit DTS packages in Business Intelligence Development Studio. You can edit SSIS packages only in BI Development Studio"
