Promoting Windows Server 2008 R2 as DC + DNS in 2003 AD Domain
I'm about to do the Domain Controller + DHCP and DNS role transfer from Windows Server 2003 Std. R2 SP2 into Windows Server 2008 Std. R2 SP 1, is there anything that i should be careful about ?
Here's the current AD Domain details:
Domain Functional Level: Windows 2000 Native (since there is Samba Server)
- ServerA: DC + 1st DNS + DHCP (this will be decommissioned) - Windows Server 2003 x86 R2 SP2
- ServerB: DC + 2nd DNS + All FSMO Role + Exchange Server 2007 SP1 - Windows Server 2003 x64 R2 SP2
I'm afraid if there is any incompatibilities in running Windows Server 2008 R2 with Server 2003 then I could not restore the Server A from backup image (Acronis True Image backup).
Any kind of help in how to run Server 2008 R2 as a DC in Windows 2003 domain side-by-side would be greatly appreciated.
