Microsoft SQL Server Migration Assistant (SSMA) is a toolkit that dramatically cuts the effort, cost, and risk of migrating from Oracle to SQL Server 2005, SQL Server 2008 or SQL Server 2008 R2. SSMA for Oracle 4.2 provides an assessment of migration efforts as well as automates schema and data migration.
Included in the pack is the "Extension Pack" that emulates some of the Oracle functionality. Extension pack can be installed from the same archive as the assistant.
