AD migration from 2003 to 2012 - Operations Masters issue

Hi there

I am in a school installing a separate server 2012 r2 to replace the existing 2003 r2 setup. I want to bring over as much as I can of the network setup so I cause as little disruption as possible when they start coming back next week.

I have been following the instructions on this video https://www.youtube.com/watch?v=OG5K6B7hgRU and to be honest it seems to have been working just perfect up until 18 minutes and 10 seconds in to the video. Here is where the Operations Masters are changed.

According to the video (and numerous other tutorials that we were looking at) the operations manager is "OldServer.local" and by clicking the Change button, this should then change to what is displayed in the lower field, which should be "NewServer.local". However, what is displayed "OldServer.local" in both fields.

I have checked the Operations Masters on the OldServer just to see what is displayed there and it is the exact same. When I do actually click Change on the NewServer I get an error message saying

The current domain Controller is the operations master. To transfer the operations master role to another computer, you must first connect to it.

So how do I connect to it? I have turned off the AV on both and rebooted both. But it made no difference.

Regards

Oh, just to let you know. I have checked the AD on the NewServer and it all seems to be there.

About a month ago I migrated an environment from 2003 to 2012 R2.

Here are the rest of my notes from that migration project.

Adding a Windows Server 2012 Domain Controller to an Existing Windows Server 2003 network

Make sure your domain AND forest functional levels are at 2003.  That messed me up for a bit.  I had only updated the domain and forgot the forest functional level.

Hi ScottCha

Thanks for all of the details. I made the same error earlier myself about function levels being set to 2003.

I will go through these as soon as I can and get back to you.

Cheers

Hi ScottCha

I have gone through what you sent me and as far as I can make out I have done everything correctly up until the point that I am having the issue. I did a bit more research and I saw that I could change the FSMO mode through the command line. I tested this out wig RID first. But this just seems to create an error in the first field and the OldServer in the second one.

Here are the steps I followed. If this domain controller is a global catalog, ensure that another global catalog is available to users before demoting it. For information about configuring domain controllers to host the global catalog
Make sure domain controller is not the ONLY Global Catalogue
https://technet.microsoft.com/en-us/library/cc758330%28v=ws.10%29.aspx

If domain controller currently holds one or more operations master roles, transfer the operations master roles to another domain controller before demoting it
https://technet.microsoft.com/en-us/library/cc781578%28v=ws.10%29.aspx
See the links at the bottom of this page--check each link to remove or move each role or you can use the command line with the steps I have provided below

Type all these from a command prompt
ntdsutil
roles
connection
connect to serverDomainControllerName
quit

Rem    Transfer the schema master role
transfer schema master

Rem    Transfer the domain naming master role
transfer domain naming master

Rem    Transfer the RID master role
transfer RID master

Rem    Transfer the PDC emulator role
transfer PDC

Rem    Transfer the infrastructure master role
transfer infrastructure master

Then finally, how to demote a domain controller if you plan to remove it from the domain
