Hi Gil,
The easiest way to do this is to create a duplicate project and maintain the dependencies. You would create a new folder then, from the project, select Save As >> Duplicate - Include All Dependencies. This will copy all of the files to the new folder while maintaining the dependencies that exist between the various files. Then, all you would have to do is add your new sbRIO to the new project and move the VIs and other LV files under the new sbRIO.
