SQL Server Migration Assistant (SSMA) is a suite of 5 tools designed to automate migrations from Oracle, Access, DB2, MySQL and SAP ASE (formerly SAP Sybase ASE) to Microsoft SQL. It automates the conversion of database schemas to a Microsoft SQL Server schemas, deployment of the schemas, data migration to the target SQL Server (see below for supported versions), and validation of migrated objects.
The latest releases of SSMA for Oracle and SSMA for DB2 improve the automatic conversion by adding support for new functions and enhancing existing conversion logic. In addition, all tools use COUNT_BIG in row count queries for the target database.
