Upgrade Active Directory DNS considerations
Posted on 2013-11-27
I am going through an upgrade of a server 2003 to Server 2012.
The current server 2003 domain has been previously upgraded from Windows 2000
Although all the DCs in the current environment are server 2003 and the FFL is server 2003, the DNS configuration is still set to replicate to all domain controllers in the Active Directory domain (a windows 2000 configuration)
I know from Server 2003 and on-wards that DNS is now stored in application directory partitions and the correct configuration should be to replicate to all DNS servers in this domain.
The forest DNS zone is also missing from the 2003 DNS servers.
If i was to install Server 2008 R2, the default settings are to replicate to all DNS servers in the domain,. The forest zone is also there.
Am i then right to say that the first step in upgrading the server 2003 domain to server 2012 to change the DNS settings ?
The missing forest DNS zone would be more of an issue if there was more than one domain?
