asked on Schema update forest and domain
I have a network which is running a 2000 forest level and a 2003 domain level. There are two 2003 Domain controllers in place now. I would like to add a 2008R2 Domain controller into the domain and also keep the 2003 Domain Controllers in place but at lower roles. I will want the 2008R2 DC to take over the FSMO roles, and then over the course of time I would like to demote the 2003 DCs and go completely with a 2008R2 infrastructure. I have read that doing a schema update on the forest level to 2008 would be bad if I want to keep a 2003 DC in place in the domain... thus can someone give me an overall solution to accomplish this task, which is to do a Schema update to accomodate a 2008R2 DC (I have memever servers in place already), transfer the FSMO roles to the 2008R2 DC, then over time demote the 2003 DCs and introduce aother 2008R2 DC. I would also like to know if it is possible to do a schema update now to 2008R2 BEFORE adding in a 2008R2 domain controller? Say, for example, I wanted to put the 2008R2 DC in place next month, but I just want to prep the forest/domain for it now... what steps would I take to do this?
Thank you...I greatly appreciate it!

Forestprep and domainprep will not affect your 2003 DCs. I would recommend updating your forest level to 2003 as well if you don't have any Windows 2000 servers as DCs

I have a 2003 DC and 2 2008 R2 DC's on the same network - it is not an issue.
Follow the steps you have outlined and you will be fine.
You will need the 2008 R2 DVD in the Windows 2003 server - if the 2003 server has a DVD! If not - find a DVD drive, share it out and run the commands from the shared DVD drive.

You can copy the files as well to the Windows 2003 server from another

Hi all - thanks for the info. I have one more question about this, because I am going to be attempting the Schema update this weekend. Do I have to update the Forest if this is just a one-domain site? Can I just leave the forest at 2000 (via forestprep) and do the Schema update to 2008 on the domain (domainprep) only?
Thanks for all the info...!

You need to run adprep /forestprep and adprep /domainprep for the domain to be ready to accept a Windows 2008 /2008 R2 Domain Controller:

Thank you both for your help - sorry it took so long to resopnd and apply the points. it's been busy with my new 2008 Domain Controller. ;) I'm going to transfer the FSMO roles this weekend, and demote the 2003 servers soon after. Thanks again for your help!
So basically you're saying I can just do:
Preparing your Active Directory infrastructure for upgrade includes the following tasks:
•Prepare the forest schema by running adprep /forestprep.
•Prepare each domain where you want to install a domain controller that runs Windows Server 2008 or Windows Server 2008 R2 by running adprep /domainprep /gpprep.
I'm concerned about the forestprep... I don't want to do something on a forest level that would kill the ability to have a 2003DC in place... I've done a forestprep and domainprep before a long time ago, and am grateful for any steps or help that you can provide. Keeping in mind what I am trying to accomplish, what would the steps be that I need to take to just update the schema this week (for example), then introduce the 2008R2 DC next week?
Thank you again!
