Moving up to Windows 2008 Server Domain

Dear Experts,

I currently have Windows 2003 domain that is currently running 2000/2003 AD mode.
Since the initial setup, Windows 2000 server has been removed and windows server 2008 member servers have been added to the network.

I have two 2003 domain controllers right now. Both running WINS and DNS.  

The goal is to upgrade to make 2008 server by adding a new 2008 to the network and taking over the AD role. (obviously it will be in 2003/2008 mixed mode AD)

what would be the steps to change to server 2008 network?  Any problems in doing this?

Thanks,

Hello,

this is a Standard Change with normal impact and low risk, but be sure to make System State Backups of your AD at any step.

- Cleanup your current Active Directory (Delete old, unused objects, remove orphaned DCS with NTDSUtil)
- Install Windows Server 2008 R2 as Domain Member
- Run Schema Update on old DC (http://blogs.technet.com/b/danstolts/archive/2011/03/05/upgrading-a-windows-2003-domain-to-windows-server-2008-r2-functional-level-domain.aspx)
- Run DC Promo on new Server to upgrade to Domain Controller
- Install DNS und WINS on the 2008 R2 Server
- Change DHCP and static IP Configurations to use new DNS Server
- Run DCPromo on old DC to demote to domain Member
- Change Domain and Forest Functional Level to 2008 R2
- If you use more than one DC: Upgrade AD Replication to DFS instead of FRS with DFSMIG
- Activate new Features like AD Recycle Bin (http://technet.microsoft.com/en-us/library/dd379481(v=ws.10).aspx)
- Check TombStoneLifetime (https://msmvps.com/blogs/ulfbsimonweidner/archive/2010/02/10/adjusting-the-tombstone-lifetime.aspx)
- Implement new Server to your Backup-Infrastructure
- Implement AV on new DC with exclusions described in http://support.microsoft.com/kb/822158
