Replacing 2003 DC wint 2008 DC

Sponsored Links

I know that this type is probably one of the common questions here but
I want to ask anyways.

I have a new box that has 2008 standard on that I just installed. The
old old DC is 2003 and also has the Primary DNS (AD intergrated) for my
network.

I would like to keep the same name and IP address on the new domain controller.

What would the best practice to accomplish this?

Thanks

Mike

Hello,

Thank you for your post.

According to the description, my understanding is that you'd like to know
how to replace Windows Server 2003 domain controller with Windows Server
2008 domain controller in your Windows Server 2003 AD domain. If I have any
misunderstanding, please feel free to let me know.

Firstly, this requirement is not a simple project. Although this newsgroup
provides break/fix resolution, we are happy to provide general information
and suggestions on it here and you may receive suggestions from other
partners on this topic here. However, please know that we are not the best
support resource for advisory issues. For this kind of issue, I highly
recommend you contact our CSS advisory service at
http://support.microsoft.com/gp/advisoryservice.

Having said the above, I'd like to share you some basic suggestions.

Basic Suggestions:
==============
The first step you need to do is to prepare the forest schema and to
prepare a Windows Server 2003 domain for Windows Server 2008. To do this
you need run "adprep /forestprep" on the windows server 2003 DC which holds
the schema operation master of the current domain and run "adprep
/domainprep" on the windows server 2003 DC which holds the infrastructure
master of current domain.

The second step is to join the Windows Server 2008 machine to the domain
and promote it to another DC. After that, please transfer the DNS records
from your current DNS server to Windows Server 2008 DNS server. To do this,
please install DNS server role on Windows Server 2008 and then Create a
secondary DNS zone on Windows Server 2008. After all DNS records have been
transferred from the old DNS Server to the new DNS Server, please change
the secondary DNS zone to primary AD intergrated DNS zone on the new DNS
Server.

The third step is to demote the old Windows Server 2003 DC to member server
and disjoin it from the current domain. If this old DC holds any FSMO
roles, please transfer FSMO roles before performing the demotion. After
that, please change the name and IP address of Windows Server 2008 DC to
old DC's previous name and IP address. Then, please restart Netlogon
service or restart the DC to update the changes.

Moreover, please note that Windows Server 2008 DC only supports Windows
Server 2003 Native mode and above domain functional level. Therefore, if
there are other Windows 2000 Server DCs exist in your current domain, you
have to demote them to member servers and raise the domain functional level
to Windows Server 2003 Native mode before you join Windows Server 2008 DC
into the domain. Also, a full backup should be performed at the beginning.

very nice post! I have two DC's on Windows Server 2003. What do you suggest
for this scenario? De-promote second DC to a member server and then follow
your procedure?
Thnx

Hello Mike,

How's everything going?

I'm wondering if the suggestion has helped or if you have any further
questions.

Please feel free to respond to the newsgroups if I can assist further.

To Jonathan,

If you have the same requirement, in other words, you'd like to replace the
old Windows Server 2003 DC with the new Windows Server 2008 DC and keep
the same name and IP address, please demote the old DC you want to replace
and disjoin it from the domain.

If you have a different requirement, please open a new thread in this
newsgroup and describe your requirement in detail in that new thread. That
way each issue can receive full attention and also make the thread more
clear and consistent for your reference. Thank you for your understanding.

Thanks for your understanding.

Thanks Jian-Ping,

my last question: is it neccessery to change the name and IP address of
Windows Server 2008 DC to old DC's previous name and IP address..?

Hello,

Thank you for the reply.

No, there is no need to change the name and IP address of Windows Server
2008 DC to old DC's previous name and IP address.

This is just one of the thread owner's requirements. It depends on your
real requirements whether the new DC's name and IP address should be
changed.

I hope this helps. Thanks.
