Root=file-spec

    Requests that the database root file be moved to the specified
    location. If not specified, the database root file is not moved.

    You must specify the Root qualifier when you use the RMU Move_
    Area command on a single-file database. If you omit the Root
    qualifier, you receive an error message. When you specify the
    Root qualifier, specify the location where you want the root file
    moved. For example:

    $ RMU/MOVE_AREA/ROOT=DISK1:[DATABASE.TEST] MF_PERSONNEL

    See the Usage Notes for information on how this qualifier
    interacts with the Directory, File, and Snapshot qualifiers.
