    Can I just upgrade my current 2003 R2 x64 servers one by one to 2008
    x64 as long as I'm sure that I have all the necessary drivers?

    Is there a list of official steps involved to move a whole 2003
    environment to 2008?

    Thank you.

    Hello Aaron,

    Thank you for your post. I will be assisting you on this issue.

    Yes, there should be no problem when you do this. However, I would like to
    suggest not doing this unless you have got RTM version of Windows Server
    2008, as build-to-build upgrade for pre-release versions of Windows Server
    2008 is not supported.

    Besides, there are some prerequisites and limitations when you perform the
    upgrading. I just list the brief information for your reference.

    Prerequisites:
    ============

    1. Test your applications.

    2. Ensure that all x64 kernel-mode software is signed.

    3. Back up your servers.

    4. Be aware that you cannot uninstall Windows Server 2008.

    5. Ensure that your applications are compatible.

    Limitations:
    ===========

    1. You cannot upgrade to a version of the operating system that has fewer
    features than the operating system you are currently running. For example,
    you can only upgrade Windows Server 2003 Datacenter Edition to Windows
    Server 2008 Datacenter Edition.

    2. The Windows Server 2003 for Itanium-based Systems operating systems and
    Windows Server 2003 Web Edition operating systems cannot be upgraded. If
    you have these editions, you must perform a clean install and migrate the
    data from these computers to the new operating system.

    3. Upgrading is supported from x86-based and x64-based computers, but
    cross-architecture upgrades are not supported. For example, you cannot
    upgrade from an x86-based computer to an x64-based computer, even if the
    server you are upgrading is x64-capable.

    4. Cross-language upgrades are not supported.

    5. You cannot upgrade the failover clusters from Windows Server 2003 to
    Windows Server 2008. Before upgrading, you must uninstall failover
    clustering. For more information, refer to article 935197 in the Microsoft
    Knowledge Base (http://go.microsoft.com/fwlink/?LinkId=110946 ).

    6. Upgrading from Windows Server 2003 to a Server Core installation of
    Windows Server 2008 is not supported.

    For more details, please refer to:

    Guide for Upgrading to Windows Server 2008:

    c-b68f-a5b4baeb52481033.mspx?mfr=true

    I hope this helps. If you have any other questions or concerns, please feel
    free to let me know.

    Thank you and have a nice day!

    I assume that in a VM should be sufficient?
    Is there any way to specifically check this? When you say software, are
    you referring to drivers?
    Will I run into problems if i uprade a server that is a DC/GC and then
    have to go back to a backup of Windows 2003 R2? I ask this question
    because I assume that the Windows Server 2008 upgrade installer does an
    update to the Active Directory and I'm wondering if this would cause
    any problems if I had to restore a server to its previous state?
    Is there an application compatibility list that you can direct me to on
    Microsoft's website?

    Hello Aaron,

    Thank you for the reply.

    I list my answers here each to your one question.

    Question 1.
    ==========
    Yes, this could be a good choice. Additionally, I would like to suggest
    contacting vendor companies to see if they have any information about this.

    Question 2.
    ==========
    Indeed, the kernel-mode software includes drivers and a number of low-level
    viruses.

    Regarding the drivers signatures, there are two tools can verify the
    signatures. Signature Verification tool (Sigverif.exe) and SignTool.

    For more details, please refer to:

    How To Verify Unsigned Device Drivers in Windows XP (this tool can also be
    used on Windows Server 2003):
    http://support.microsoft.com/kb/308514

    Verifying the Signature of a Test-Signed Driver File:
    http://msdn2.microsoft.com/en-us/library/aa906245.aspx

    Regarding the low-level viruses, I would like to suggest contacting vendor
    companies to check the signature.

    Question 3.
    ==========

    As you mentioned, once you upgrade the DC in the existing Windows 2003
    domain, the Active Directory (schema and some domain related information)
    will be upgraded. So, if you only restore this server, the server will have
    a different Active Directory database than the upgraded domain. This will
    cause some unexpected problems. We generally need to backup and restore all
    DCs in the environment. However, it is not recommended to restore a schema
    master as it can result in orphaned objects.

    I would like to suggest that you make a test environment for this upgrading
    work first as it's hard to make the entire environment back to the previous
    state.

    Please read the following article in detail before you make the upgrading
    work,

    Guide for Upgrading to Windows Server 2008:
    http://technet2.microsoft.com/windowsserver2008/en/library/f1713937-0b3f-4b0
    d-9d31-410598278f6e1033.mspx?mfr=true

    Question 4.
    ==========

    We have a technical guidance about how to confirm your applications are
    compatible with Windows Server 2008. The "Works with" tool will help you
    quickly determine baseline compatibility with Windows Server 2008. For more
    details, please refer to:

    Windows Server 2008 Application Compatibility:
    http://msdn2.microsoft.com/en-us/windowsserver/cc148992.aspx

    I hope this helps.

    Thank you and have a nice day!
