This might happen when using SQL Server Express 2005 as the database server.
When you install SQL Server Express the default instance name is Servername\SQLEXPRESS. The instance name should be reflected in the Migration Manager configuration.
Note: SQL Server Express 2005 is not currently supported and should not be used.
