  • So, there is no direct migration path from W2003 to W2012 R2

    I wonder if  W2003 R2 to W012 R2 migration paths is supported.

    Direct inplace upgrade of W2K3 R2 -> W2K12 R2 is not possible.

    What you should do:

    • Install new W2K12R2 server
    • Promote it as domain controller
    • Decomission your W2K3R2 domain controller
    • Raise the domain functional level to W2K12R2

    My example is a simple scenario with one W2K3R2 DC, if you have more than one, you should install new W2K12R2s besides them, promote those and uninstall the old ones. After all the DCs are at W2K12R2 level, you can raise your domain functional level.

  • You can transition your Active Directory environment from Windows Server 2003 to Windows Server 2012 and Windows Server 2012 R2. A detailed step-by-step is available here. In-place upgrades are not an option, since these are not supported from Windows Server 2003 to Windows Server 2012 R2.

    Although the above document speaks of Windows Server 2012, you can use it to transition to Windows Server 2012 R2. As an additional step, however, I would add to migrate SYSVOL Replication from FRS to DFSR, since Windows Server 2012 R2 is the last Windows Server version to support FRS. Mpre information and a migration guide.
