NT4 -> W2K file server migration - problems with paths being too long

Discussion in 'Server Migration' started by Jacob Saaby Nielsen, Jul 9, 2004.

  1. Hey everyone,

    I'm really really really hoping you can help me out here. The
    situation is, I'm migrating an NT4 fileserver to Windows 2000. Yes, I
    would've like to go to 2003, but the new fileserver's running 2000,
    and I have no say in that matter. FSMT would've been real nice though
    ;o)

    I've been using robocopy to copy files. However, this is the problem:

    When I do properties on the new drive, it says it has 46gb data.
    When I do properties on the old drive, it says it has 90gb data.

    So, approximately 44gb data is missing. My guess is, it's caused by
    paths that are too long. Some users map directly into the folder
    structures, creating pathnames that are waaaaay too long.

    Of course the compare tools I've been using to check the result,
    reports everything fine. All folders are equally large. My guess is
    (yes, I'm guessing a lot here ;o) ), it's because only the NT4 box
    reports the true size of the drive, while the tools I've been using,
    are ignoring the folders with paths longer than 256 characters. So the
    tools all think it's gotten everything. But they haven't.

    Do any of you guys have ANY advice as to what I can do about this ?

    Best of all, of course: How can I migrate the files, including the
    paths that are too long.

    Second best: How can I find the folders that are too long, without
    having to manually travers the folder structure, so I can manually
    rename those folders and have them included in the robocopy job.

    I'm really out of ideas here. I've tried almost any tool I've been
    able to find. If you know of one, I'd be happy to hear about it.

    Or better, if you have any experience with this problem, or the
    solution to it, I'd love to hear about that too.

    In frustration,
    Jacob

  2. Hi Jacob,

    Thanks for your posting here.

    You can first use copy.exe to copy the data from WinNT to Windows 2003. Is
    the size normally?

    If so, you can use the robocopy tool with /SECFIX switch to copy only
    security information for destination files and directories.

    Please refer to the following article for more information.

  3. Hey Bob :eek:)

    Thanks for the answer. But I used Robocopy from the start, shouldn't
    that be the same as using normal copy ?

    Regards

  4. Hi Jacob,

    I think the important thing is that we first should ensure the copied files
    are integrated. So it will be better that you perform a normal copy again.
    Or it is no meaning to check the permissions.

    What do you think?

  5. Well, I don't think it's a problem with permissions. I'm domain admin,
    and have taken ownership of all files, plus ensured that domain admins
    have full control of all files and folders.

    I had problems with one directory not being copied, which was way too
    long. Because users map directly into the folder structure, and create
    folders with names so long it's silly ;o)

    Robocopy can copy all of the files, it seems, except those that are in
    a path that's too long. I'm trying to go through all of the folder
    structure manually right now, to check whether I'm right about it, or
    it in fact is a problem with permissions.

    But thanks, none the less :eek:) And I'll report back what I found out...

  6. Hi Jacob,

    You can also try the tree command to dump the whole folder structure and
    compare if there is some thing missing.

    Wish it helps.

  7. Hey Bob,

    I tried manually copying everything, the exact same result. I've been
    using the program Beyond Compare, and everything's the same, to the
    byte.

    There's a whole lot of files on the drive. Could differences in
    cluster sizes on NT4 NTFS vs. Win2000 NTFS cause such a massive
    difference in reported size ?

  8. Hi Jacob,

    I think it should not be related to the differences between NT4 NTFS and
    Windows 2000 NTFS. The size is changed too much.

    When you check the files size, do you right click the whole folder and
    click properties to check the size?
    Did you use the compressed partition in WinNT server?
    Did you find any thing missed?

    Best regards,
