TOPIC


    This document was not written by Apple or tested for accuracy, but it's included because we feel you might find it useful for converting a Novell DataClub file sharing environment to an AppleShare server.

DISCUSSION


    This document describes some methods for converting a Novell DataClub file sharing environment into an AppleShare server. It also presents some instructions for removing the DataClub software from a Macintosh, after the data, users, and security information have been successfully converted to the new file-sharing environment.

    Backup and Restoration Methods
    ------------------------------
    We suggest three methods for converting data stored on a DataClub file server volume into an AppleShare volume. Each method has its own benefits, but all have the same drawback: none of these methods preserves the security information established by the DataClub software. Therefore, we strongly recommend that you use the DataClub Admin utility to obtain a thorough summary of all information about users, groups, and the security of shared files and folders before destroying any DataClub volume(s). You must then explicitly recreate all the user names and security assignments for files and folders that you previously established using DataClub on the new AppleShare server; this is essential in order to minimize difficulties for end users during and after the conversion process.

    1) You can back up the DataClub volume, whether it is a dedicated server
    volume or a distributed or "virtual" volume, by using a number of tape
    drive utilities. Retrospect, from Dantz Software, is one example of a
    DataClub-compatible tape back-up system.

    When using a tape back-up system, be particularly aware of any
    restrictions on how you can restore the data to a different volume. Each
    tape back-up vendor's solution may incorporate differing rules concerning
    existing volume names, new volume names, or incremental restorations. So
    be sure to verify that you can successfully restore all the data to the
    new volume before destroying the old DataClub volume.

    2) You can copy the data on a DataClub volume directly to the new
    AppleShare volume. To do this, mount both the DataClub and the AppleShare
    volumes on the desktop of the client Macintosh. Then, simply drag-copy
    the dataÐand directory structure, if you wantÐfrom one volume to the
    other.

    This method may be slower than others, but it allows you to verify the
    data's integrity on the new volume at arbitrary times during the process.
    If a problem occurs, you can halt the process and troubleshoot the
    problem at that time.

    3) You can move the data on the DataClub volume to some other intermediate
    storage, such as a workstation user's local hard disk or some removable
    storage such as a writeable magneto-optical drive. You can even copy all
    the DataClub data to 1.44 MB floppy disks. After moving the data to
    intermediate storage, you can easily copy the data to the new AppleShare
    volume.

    This method is probably the most labor-intensive of the three. However,
    if you do not have a tape back-up utility and want to install the
    AppleShare server software on the same machine as the current DataClub
    DSM (Dedicated Server Module) software, this method may offer the most
    desirable solution. In this case you can verify the data's integrity on
    the intermediate media at arbitrary times during the copying process.
    Then, during the software conversion from DataClub to AppleShare, you can
    retain the media in a safe place. Finally, after you install the new
    AppleShare file server, you can recopy the data to the new volume.

    Removing DataClub from the Macintosh
    ------------------------------------
    It is important that you not remove the DataClub software or the hidden volume before successfully restoring the data on a new volume where you can verify the data's integrity.

    We suggest two methods for removing the DataClub software from a Macintosh volume. Both of them require a resource editor program like ResEdit from Apple Computer or Norton Utilities from Symantec.

    1) Use your favorite resource editor on each Macintosh where DataClub is
    installed. First, turn DataClub off in its Control Panel and restart the
    Macintosh. Then use the resource editor to find the hidden DataClub
    folder. (The folder name may include five non-printing boxes.) After you
    find the folder, use the resource editor to make the folder visible so
    that you or the workstation user can move the folder to the Trash, as
    with any other folder on the local volume. The time required to empty
    the Trash depends on how much data the folder contains. This method may
    be the faster of the two, but it requires a person familiar with
    resource editors to perform the operation on every Macintosh where
    DataClub is installed.

    2) If DataClub is installed on every Macintosh, and each Macintosh has made
    its hard disk available for use by DataClub, you can remove the DataClub
    software from each Macintosh in a step-wise fashion. We recommend that
    you remove DataClub software from Macintosh workstations in order, based
    on the amount of available disk space on each Macintosh:

    (1) first, remove DataClub from the Macintosh with the least available
    disk space.

    (2) proceed to the Macintosh with the second least available disk space,
    and continue in this order;

    (3) finally, remove DataClub from the Macintosh with the most available
    disk space.

    Starting with the first Macintosh, open its DataClub Control Panel and
    uncheck the checked disks in "Use these disks" list. This will cause
    DataClub to move any shared data residing on the first Macintosh to
    other Macintosh clients on the DataClub network. After DataClub has
    moved the data, turn off DataClub by clicking the OFF radio button in
    the DataClub Control Panel. If at any point during the automatic data
    migration a problem arises, use a resource editor (as described in the
    first method, above) to remove DataClub from the volume. After
    restarting the Macintosh and verifying that DataClub does not load, move
    the DataClub Control Panel into the Trash. If any DataClub applications
    like the Admin utility reside on the Macintosh, throw them away also
    because they are not useful without the DataClub software.

    Repeat the steps in this method on every other Macintosh client until
    all the data (files and folders) reside on the last Macintosh on the
    network. On this workstation, turn DataClub off in the Control Panel,
    and restart the machine. Use a resource editor to find the hidden
    DataClub folder on the root of the volume and make it visible. After
    quitting the resource editor, simply move the entire DataClub folder
    into the Trash. The time required to empty the Trash depends on how many
    files are in the folder.
