  • Hi,

    Please understand that we couldn’t do in-place upgrades of Windows Server 2003 DCs, however we could introduce Windows Server 2012 DCs into the environment and then remove the existing DCs when we’re ready.

    For details, I suggest we’d better refer to the following articles.

    Direct in-place upgrades (reusing the same hardware) are not supported between Windows Server 2003 and Windows Server 2012.

    You have two options exist to migrate the Active Directory:

      • When the Domain Controllers are running the 64bit (x64) version of Windows Server 2003, you can in-place upgrade them to Windows Server 2008 x64, and then onwards to Windows Server 2012. (64bit only) 
      • When the Active Directory environment is running the Windows Server 2003 domain functional level you can transition to Windows Server 2012-based Domain Controllers. The process is to add new Windows Server 2012-based servers, run adprep from these servers (or a Windows 8 installation), after replication has occured, install the Active Directory Domain Services role on them and then promote (at least two) servers to Domain Controllers for the domain. Then, again when replication has occured, you can move the FSMO roles from the Windows Server 2003-based Domain Controllers to the Windows Server 2012-based Domain Controllers. After you've migrated all other roles, features, software and services, you can then demote the Windows Server 2003-based Domain Controllers and raise the functional levels to Windows Server 2012.

    I'm planning to upgrade it to Windows 2012 domain controller and Exchange 2012 SP3.

    Assuming you're referring to Exchange Server 2010 SP2 (Exchange Server 2012 doesn't exist and SP3 for Exchange Server 2010 hasn't released yet, so Exchange Server 2010 SP2 is the latest and greatest at this moment), it's pretty straightforward to migrate from Exchange Server 2003. You can already implement Exchange Server 2010 in your Windows Server 2003-based domain on a Windows Server 2008 R2 installation. (Sources here and here) Active Directory can be migrated after the Exchange migration has finished.

  • he guys

    i have same things and Currently Exchange 2007 Sp3 is running wit Windows 2003 R2 Domain Controllers ( FF Windows 2003 ). can i migration AD first( will exchange 2007 SP3 support for Windows 2012 DC) . or better to Migration Exchange 2010 SP2 first ( on top of Windows 2008 R2-SP1- Since Exchange 2010 SP2 doesn't support on top of Windows 2012 and have to wait for Exchange 2010 SP3 ). then the AD Migration.

    thank you
