Error using dtutil to copy ssis packages from one server to another

Hi all,

Trying to simply copy SSIS packages and folders from one sql 2008 server to another sql 2008.

Executing this:

EXEC [master].[sys].[xp_cmdshell] 'dtutil /SourceServer SERVER_A/SQL;"\ROOT FOLDER\SUB FOLDER\MY PACKAGE NAME - HAS SPACES" /DestServer SERVER_B/COPY SQL;"\ROOT FOLDER\SUB FOLDER\MY PACKAGE NAME - HAS SPACES"'

Error I'm getting:

output
Microsoft (R) SQL Server SSIS Package Utilities
Version 10.0.5420.0 for 32-bit
Copyright (C) Microsoft Corp 1984-2004. All rights reserved.
NULL
Option "\ROOT FOLDER\SUB FOLDER\MY PACKAGE NAME - HAS SPACES" is not valid.
NULL

Thanks for any help,
