Promoting new Server 2012 R2 as DOmain Controller nad Global Catalog steps ?
Hi,
Can anyone here please share the steps and the caveats when promoting Windows Server 2012 R2 as domain controller in my existing Single Forest AD domain ?
The current domain & forest functionality level is Windows Server 2003.
My current Domain controller are as follows:
HeadQuarter Office AD Site where all of the workstations resides:
OLDDC01: Windows Server 2003 – Running as: DC/GC, PDC, RID & Infrastructure Master Role and Primary DNS & DHCP (for all of the servers in HQ and the Workstations) to be decommissioned.
NEWDC02: Windows Server 2012 R2 – Running as: normal domain joined server (member server)
Data Center AD Site where all of the servers resides:
PRODDC01-VM: Windows Server 2008 R2 – Running as: DC/GC, Schema Master Role and Secondary DNS for all of the servers.
PRODDC02-VM: Windows Server 2003 R2 – Running as: DC/GC, Domain Naming Master Role (to be decommissioned)
PRODDC03-VM: Windows Server 2008 R2 – Running as: DC/GC, Primary DNS for all of the servers
In this first stage, I just need to Promote the NEWDC02 in my HQ to be the DC/GC and let it run, next week I’ll post new question for transferring the roles that is held by OLDDC01.
Any kind of help and assistance would be greatly appreciated.

after 24 hours or so, i would do dcdiag on both for any errors
you might see some transient warnings though but should go away after a day or two

Hi,
I've found this article which is detailing the steps for my case in setting up the Win 2012 R2 Domain Controller:
However, in steps #12 Define if server should be a Domain Name System DNS server what could be the side effect to the existing AD integrated DNS server ? Shall I check it as yes ?
I'm not ready or dont know how to perform DNS transfer yet and don't want to cause any downtime for the existing HeadQuarter Office AD Site where all of the workstations resides.

What happened if I select the Option to make the server as DNS server during the Add new role wizard ?
Would there be any issue or outage to the DNS alredy configured in the head office ?

ok, so about the DNS server, it won't disrupt the network operation or the other server acting as the DNS server right ?

ok, what about the new server itself NEWDC02 ?
Before the DCPromo:
After the DCPromo and new DNS role is set:
would that be a good idea to prevent outage or issue ?
Before the DCPromo:
the Primary DNS: OLDDC01 IP address
the Secondary DNS: PRODDC03-VM IP address
the Secondary DNS: PRODDC03-VM IP address
After the DCPromo and new DNS role is set:
the Primary DNS: NEWDC02 IP address (it self)
the Secondary DNS: PRODDC03-VM IP address
the Secondary DNS: PRODDC03-VM IP address
would that be a good idea to prevent outage or issue ?

Because I'm not ready yet to cutover the DNS from the OLDDC01 to the newly promoted DC yet (NEWDC02).
As per this https://technet.microsoft.com/en-us/library/hh472162.aspx steps #12
Can I just click Update DNS delegation or skip it ?
As per this https://technet.microsoft.com/en-us/library/hh472162.aspx steps #12
On the DNS Options page (which appears only if you install a DNS server), click Update DNS delegation as needed. If you do, provide credentials that have permission to create DNS delegation records in the parent DNS zone.
If a DNS server that hosts the parent zone cannot be contacted, the Update DNS Delegation option is not available.

Once it is promoted as DC & GC, how can I force replicate the AD data ?
