Removing the SSMA for MySQL Components (MySQLToSQL)
When you have finished migrating databases from MySQL to SQL Server, you might want to uninstall SSMA components. You can uninstall the client components at any time. However, if you uninstall the extension pack from SQL Server , then, SSMA will no longer support migration of data from MySQL to the target database (SQL Server/SQL Azure) using the Server-Side Data Migration Engine.

After the uninstallation process is completed, you can confirm that objects in the sysdb.ssma_MySQL schema, and possibly the whole sysdb database, has been removed by using SQL Server Management Studio. However, if you use other SSMA products, they also use the sysdb database. If the database exists and you are sure that no other databases reference to the objects in this database, you can detach the database.
