Removing SSMA for DB2 Components (DB2ToSQL)
When you have finished migrating databases from DB2 to SQL Server, you might want to uninstall SSMA components. You can uninstall the client components at any time. However, you should not uninstall the extension pack from SQL Server unless your migrated databases no longer use functions in the ssma_DB2 schema of the sysdb database.
Uninstalling the SSMA for DB2 Client
You can uninstall SSMA by using Add or Remove Programs.
To uninstall SSMA
In Control Panel, open Add or Remove Programs.
Select Microsoft SQL Server Migration Assistant for DB2, and then click Remove.
To confirm that you want to uninstall SSMA, click Yes.
Uninstalling the Extension Pack
If you are sure your migrated databases do not use objects in the sysdb.ssma_DB2 schema, you can remove the extension pack by deleting it from the schema - there is no Windows uninstall.
