SQL Server Migration Assistant
Looks pretty obvious what it's targeted at if you read the FAQ:
"SQL Server Migration Assistant (SSMA) defines and automates all of the major steps in the database migration process. SSMA provides comprehensive assessment reports, one-click conversion of all schema and data, one-click conversion of almost all database-resident business logic, and automated testing of the converted code. All of these capabilities are made available from within a single-migration integrated development environment (IDE). Currently SSMA supports only a migration from an Oracle database to SQL Server 2000."
