The document discusses the migration of SQL Server 2000 Data Transformation Services (DTS) packages to SQL Server Integration Services (SSIS), highlighting the performance improvements and architectural changes that make SSIS more efficient for ETL processes. It outlines two main methods for migration: the built-in DTS Package Migration Wizard for simple packages and the DTS Xchange from Pragmatic Works for more complex migrations with best practices applied. The paper ultimately emphasizes the advantages of upgrading to SSIS for enhanced data processing capabilities.
