Replace 2003 Domain Controller with 2008R2 and Keep Same Name
Posted on 2012-04-11
I have a mixed 2003/2008 domain environment. I have already updated my schema and all that stuff, and presently have 3 2008 domain controllers. What I have not yet done is replace our remote existing 2003 domain controllers with new servers with 2008R2. I need to do this and keep the same name of the server, since they are also, file/print servers, as well as dhcp and dns servers. What are the steps required to have the new 2008 domain controller have the same name as the old 2003 domain controller.
If I do recall, the order is:
dcpromo the 2008R2 as an additional DC at that site.
Add all AD, DHCP, DNS and wait for replication to finish from old DC to new one.
We then dcpromo OUT the 2003 domain controller,
rename to a different name (2003DCOLD) and
then rename the new 2008 DC to the old server's name (RDC03) and
then copy the files and dhcp database
authorize dhcp server
Please advise if this is correct and if I missed anything.
