  • SQL Server 2017 support is now official with the Oracle Extension Pack supported on Linux as well (new remote installation option). Extension Pack functionality is limited when installed on Linux, as the tester and server-side data migration features aren't supported.

  • Added support for SQL Server 2016.

    SSMA doesn't copy history data from Oracle Flashback Data Archive tables. As a result, the history data must be copied manually during the migration process. In addition, while SSMA doesn't display the history table in the SQL Server metadata explorer because it's treated as a system table, you can view the history table in SQL Server Management Studio.

    SQL Server 2016 doesn't support several Oracle Flashback features, including:

    • Oracle Flashback Transaction Query
    • DBMS_FLASHBACK Package
