What updates do I need for 2003 Domain Controllers to prepare for 2012 DCs upgrade? Need a list of specific updates that would prevent us from running ADPREP/ forestprep etc.

You can't do in-place upgrades of your Win 2k3 domain controllers, however you can introduce 2012 DCs into the environment and then remove the existing DCs when you're ready,

https://technet.microsoft.com/en-us/library/hh994618.aspx

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.

To upgrade Window Active Directory 2003 to Active Directory 2012, Follow these steps:

Thanks. but I guess I didn't put my question right. i  know all this that you can't do the in place upgrade and we will be bringing new 2012 DCs and not using old ones..I have all this info already. What I am asking if there are hotfixes and specific updates are needed for old DCs and Active directory before we run ADPREP /forestprep for 2012 for example hot fixes in case we need to recover forest back and hotfix for 2008 DNS servers, etc.

We are using SCCM for pushing specific updates to DCs NOT all updates. So, I need to know if we to get specific updates before adprep.

THank you very much.
