SQL Server Migration Assistant (SSMA) is a complete suite of tools that dramatically cuts the effort, cost, and risk of migrating from Oracle to SQL Server. SSMA automates almost every aspect of the migration process including assessment, schema and data migration, business logic conversion, and validation. Companies such as Motorola and Simon & Schuster have used SSMA to migrate their business-critical databases quickly, easily and accurately.
