Agenda Mapping DTS Knowledge and Skills to SSIS Running DTS Packages in SQL 2005 or 2008 Upgrading DTS Packages Upgrading Active. X Scripts

Why Choose SSIS? 64 bit support Parallel in-memory multi buffer architecture helps to load data several times faster than DTS Logging, configuration, Check. Point 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 Active. X

DTS vs. SSIS Engine 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 Package needs to run from the destination server Average Runtime (seconds) DTS SSIS SQL Server Destination SSIS OLE DB Destination 33. 2 s 11. 3 s 12. 3 s

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 DTS x. Change Minutes per package Starting from scratch About 3 -6 hrs per package conservatively

Running Packages Under 2005+ Need to download DTS Designer Components (part of SQL Server 2005 Feature Pack) Pro: Delays the upgrade hurdle Con: Cannot create new packages (easily) Logging views historically in SQL Server 2000 not available Runs in 32 bit mode only (WOW) Support ceases in v. Next

Common Errors Need to Install the 2005 Backward Compatibility Kit 2005 DTS Designer Components In SQL 2008, copy two additional DLL files over and RLL files

Microsoft Package Upgrade Wizard Built into SQL Server 2005/2008 Pros: Free Works on simple packages Cons: 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% chance of working

Sample Upgrade Project Plan Scope and Number of Packages How long will it take you to migrate each type of task Use a tool to migrate Upgrade the Active. X Script Task logic Test, test and test

DTS x. Change Feature Highlights Profiles DTS packages to help with a conversion project plan Rapidly converts DTS Packages to SSIS (2005 or 2008) and applies SSIS best practices Converts tasks that are not handled by the existing SQL Server conversion wizard Includes a SSIS logging repository and reports for trending and alerting Includes BI x. Press for new SSIS packages

Monitor Packages

demo DTS x. Change Profile, Convert and Monitor

A Few of the Conversion Rules Support for migration of children packages Logging to SQL Server, Text Files or via Event Handlers Consolidate Connection Managers Create configuration files automatically Create package transactions Checkpoints NULL handling

Other Advantages Handles text files properly Handles NULLs properly Handles ODBC for a source Migrates Dynamic Properties Tasks Advanced profiler to estimate your project Full validation of the output of the migration 94%+ package success rate in customer migrations over tens of thousands of packages

Monitor Packages Error/Warning Trend Extract/Load Trend Runtime Trend

Active. X Script Migration All tools mentioned migrate DTS Active. X to Active. X in SSIS Active. X migrates to SSIS but you would not want to keep it there and it may not run Need for Active. X Script Task has been replaced with built-in, easy to maintain SSIS tasks File System Object = File System Task Mail objects = Send Mail Task (now has SMTP) ADO objects = Execute SQL Task
