Help adout migrate from NT4 to SBS

Discussion in 'Windows Small Business Server' started by Alessandro Belli, Apr 8, 2004.

  1. I have to migrate a NT4 server to a sbs2003 server, on a new hardware.
    Microsoft documents tell to install SBS, create a new domain with different
    netbios name and then migrate with AMDT, also from w2000 srv to SBS2003.
    Instead of this, can I upgrade then NT4 server to 2000 server ( and this
    convert all accounts to AD) , then add the SBS to the 2000 domain ,
    sincronyze AD and then remove the old server with dcpromo? Any experience
    about this? Or where can I find docs?
    Thank you

  2. You can't upgrade NT4 to SBS 2003. You'll have to go with the document
    migration from SBS 4.5 (NT4 /Exchange 5.5) to SBS 2003. This works
    perfectly. It will transfer the user and computeraccounts and the mailboxes
    and shared folders.
    Do you have that document yet?

  3. I don't want to upgrade NT4 to SBS, but NT4 to 2000 and then add the new
    SBS2003 to the existing domain.
    I've read somewhere that SBS2003 allow to have an other 2000 domain root
    server for a shot time, in order to allow this operation.
    Yes, I have the document, I hoped to do the migration without change then
    netbios domain name, but as you write it is not possible, isnt'it?
    Thank you

  4. What is wrong with changing the domainname? You're going to a double process
    if you first upgrade to SBS 2000 and then to 2003.

    I do not believe that SBS 2003 will allow any other server
    to be root of the domain, so joining it to another domain
    is not possible - I will check, but this is the golden
    rule as I understand it. You can have other AD servers in
    an SBS 2003 domain :)

  6. I don't have to upgrade to SBS2000: my actual server is a NT4 server (not
    SBS), so I'd like to upgrade this to 2000 server.
    The problem is not also about the domain name: I 'd like keep the old nt4
    (upgraded to 2000) still working on the network to have more time to
    complete all the migration from the old server to the new one.

    How about this as a process - I am assuming your SBS 2003
    system will be on a new server:
    1) add new server - load NT4 (I assume you have a legal
    copy of this & other OS's)
    2) DC promo to a BDC
    3) turn off existing PDC (just in case it all goes pear
    4) BDC -> PDC
    5) In place upgrade to W2K
    6) In place upgrade to SSB 2003 as per :

    How does this sound?

    From a licensing point of view, you would need a legit NT4
    & W2K license for new system for use during upgrade
    process, although a eval copy might be sufficient here and
    there may be "downgrade" rights to NT4 from a W2K
    license. Also W2K could be a copy of W2K3 I believe.

    Potential issues:
    1) I might have process wrong
    2) NT drivers for new hardware might not exist

    You can not have two machines on the network with the same

    I have given you a process in my other post that might
    help get your users to SBS 2003 without them having to
    change settings. If you then wanted to use resources on
    the NT4 box in W2k mode, you would need to DCPromo the box
    down to a member server, then upgrade to W2K(3) and then
    DCpromo to join SBS 2003 domain.

  9. Yes, it sounds much more complex,
    the idea of upgrade NT4 to 2000 is usefull only if then is possible to
    join the new SBS2003 to the 2000 AD.
    Thank you .

    The whole point is that SBS is not joining another domain,
    but it is the root of the domain. One of the few rules of
    SBS vs WIndows Server std.

    By doing it this way, the PDC is the root of the NT4
    domain, the new system becomes the new root of the NT4
    domain and then is upgraded - all on the new system so SBS
    is happy at being the root.

    Hi There,

    It has taken me ITRO 1 week to finish a "hot swap" of an
    NT4 domain with Ex 5.5 to SBS 2003. With no real
    experience of this, it has gone through ok and there are a
    few little Admin niggles left to sort but nothing in terms
    of users.

    I completed this on my own in a 24/7 environment running a
    separate SQL box and also changed the domain name (due to
    the fact that the old domain name had NT in it)

    The basic way I did it (depending on the no. of clients
    you have (I had 25) and if you have a new server) was
    quite a manual way but it worked:

    1) dcpromo the new SBS2003 server keeping it off of the
    existing network

    2) Create all users in AD - ip ranges etc

    3) Complete necessary updating

    4) Create .pst files on the users computers for emails /
    Public folders. Take old PDC offline. Make copies of
    favs / desktop / docs and put in root of c: on client pcs.

    5) join servers / PC's to new domain.

    6) Set up desktops and reimport .pst

    It took a approx. 8 full hours through the night to do the
    above on my own and also I had to reset share permissions
    and SQL security.
    The bulk of it though was in the morning when the general
    users queries came.

    Don't forget to take the old PDC/BDC offline because it
    repopulated the dns on the all the servers and I got
    called in the day after at 0230 because nothing worked..

    I was a satifying experience but very hard work yet
    worthwhile now.

    Hope that is ok but it is very brief,
