SBS 2K3 Migration to SBS 2K8

    I'm planning migrating my existing SBS 2003 Premium to SBS 2008 and have
    read the microsoft migration paper. In the paper is requires moving to a
    single network LAN connection to the Internet and using the 192.168.x.y IP
    range. This is so that the SBS 2008 install wizard can find the router that
    is deemed to be on the same subnet.

    My current 2 NIC setup would require that I migrate to a single NIC and also
    change the existing 10.0.0.x private address range to the 192.168.x.y range.

    Are there any papers or reports on how to do this easily using the migration
    process? Is is possible to change the SBS 2003 premium ISA 2004 2 NIC setup
    to a single NIC and also change the LAN address range?

    As far as I know, discovery tries a.b.c.1 to 9, so 10.0.0.x would be
    discovered, with your existing SBS being the DHCP server. So you could
    change your lan IP scope, or not.

    But there's work to be done anyway, as you know, you have to drop to a
    single nic configuration prior to starting the migration.

    You'll first want to uninstall the ISA client everywhere, then uninstall ISA
    itself (and removing any proxy settings you have on boxes\applications that
    use them). Once you've got ISA uninstalled, you can run the CEICW to enable
    internet access and then take a breather, if you wish :).

    When it comes time to drop to a single NIC configuration, you'll need to
    either change the LAN ip scope to match the router, or changing the router
    scope to match the LAN (shutting off DHCP on the router, if it's on).

    Once done, then change the physical layout so that the router is connected
    at the switch, along with all the computers including the SBS. There's a
    change IP wizard for the SBS (which will reconfigure DHCP and look after the
    workstations), but if you have any static IPs/reservations you'll need to
    visit those. Disable the NIC that was previously the external NIC.

    CEICW after the change IP wizard and replugging cables should get you going,
    and you'll then be ready to plug the new hardware into the switch and start
    the installation/migration.

    Hi Les,

    Thanks for the prompt response! Sounds a piece of cake!?

    I shall give it a go and let you know down the track.

    It's not a piece of cake ;-/. It's a rather complex operation with some
    automation provided but still a number of manual steps using tools not
    everyone is familiar with. While there is a guide, it has frequent links to
    other technet documentation, where only bits of the linked to documentation

    IMO, the best way forward with SBS 2003 to SBS 2008 is to practice it in a
    virtual environment, following the guide but also making your own notes
    along the way. Your notes will be your personal guide to future production
    migrations, and the virtual environment will provide a way to start over
    without running the risk of taking someone out of production.

    Don't expect to succeed on the first attempt. If you do, great - but don't
    expect it. My 3rd attempt was good enough to put into production.

    Sounds like and actual are not the same. Migrations are NOT simple and
    require the 6 Ps (Proper Prior Preparation Prevents Poor Perforfance) If you
    are an Experienced SBS consultant just be aware that 2k8 is different!

  6. you're missing one of the 7 Ps. ;)

    and you're right. You need to plan and READ the migration docs carefully
    before you start. Understand them, and the process as a whole. Then follow
    them carefully.

    Hi Guys,

    Appreciate the comments from everyone. I have learnt through using the
    SBSMigration process from JM that it requires practice and personal

    You comment on using a virtual environment as a practice environment is
    valuable and I will take that approach as my means of learning what not to
    do as well as how to do it.

    Thanks again,
