I was running the Upgrade Advisor for SQL 2008 and found this error: "Package contains unregistered custom task or Analysis Services Processing task". Almost 140 SQL Server 2000 DTS Packages are reporting the same error. I am trying to seach it on the net but I am not finding any concrete solutions. I want now to Upgrade from SQL 2000 to SQL 2008 - Are these DTS Packages not going to give me problems when I migrate them on Legacy Mode? Help please........
