SQL Express does not include the Management Studio by default.
Either install SQL Server Management Studio (2005-2008) on the Recovery Manager for AD Server or connect to the SQL Express instance remotely.
The username used to install RMAD orginally is the same as the connect to username / password used to connect to the SQL Server Express Instance remotely
Backup the RecoveryManager-Reporting Database
The name of this DB is normally, RecoveryManager-Reporting-YOUR_SERVER_NAME_HERE
Restore the Database to the new Destination SQL Server.
A Change in the Registry is also required to point the Application to the new SQL Server and Database name.
