  3. Why choose SSIS? • 64bit support • Parallel in-memory multi buffer architecture helps to load data several times faster than DTS. • Logging, Configuration, CheckPoint etc. • Source Safe Integration because everything is XML • Many new Tasks (e.g. Script Task, For Each Loop, XML Task etc.) that replace need for ActiveX Less Maintenance… Faster Development… Faster Performance

  4. DTS vs. SSIS Speed Test • On 32 bit dual core machine • Pulling 1 million rows out and writing to SQL table with no transformation • SSIS 65% + faster than DTS • Adding transformation would add more SSIS advantage

  5. Project Options • Run DTS in 2005 or 2008 • Missing the package logs • Runs under 32 bit • Upgrade using MS Wizard • Not compatible with most package • Upgrade using DTSxchange • Minutes per package • Starting from scratch • About 3-5 hrs per package

  6. Demo • Running DTS package in SQL Server 2005/2008

  7. Microsoft Package Upgrade Wizard • Built into SQL Server 2005/2008 • Does not handle ODBC • Only handles a few types of text file use cases • No Dynamic Properties Task • No UDL or legacy database support in data pump • Packages only have about a 20% of working

  8. What is Involved in Upgrading? • Scope and Number of Packages • How long will it take you to migrate each type of task • How to migrate, Manual or Tool • Upgrade the ActiveX Script Task logic, Manual • Test, test and test
