Migrating DNS from Server 2003 to Server 2012 R2
Once you've completed the assessment of your organization's DNS deployment, it's time to migrate the DNS role from computers running Server 2003 to computers running Windows Server 2012 R2.
Assessing 2003 DNS infrastructure prior to migration
Prior to migrating from Server 2003 to Server 2012 R2, you’ll need to figure out which servers in your organization are functioning as DNS servers. You’ll also have to figure out which DNS zones are hosted on your DNS servers and the nature of those zones.
Migrating Server 2003 File Server Workloads
Migrating a file server workload from Server 2003 to Server 2012 R2 requires a bit more than simply copying the files from the computer running Server 2003 to the computer running Server 2012 R2.
Understanding new file server options
If you’ve kept your file servers running Windows Server 2003, you probably aren’t fully aware of the options that have become available in more recent versions of the Windows Server operating system.
Triaging File Server Workloads
Perhaps the most common Windows Server role is that of the humble file server.
Windows Server 2003 Migrations: Upgrading Domain & Forest Functional Levels
Once you’ve removed all of the Windows Server 2003 domain controllers from your environment, you can upgrade the domain and the forest functional levels.
Removing legacy domain controllers 2
Once you’ve added a sufficient number of Windows Server 2012 R2 domain controllers to your organization’s Active Directory forest, migrated the FSMO roles, ensured any custom partitions are also hosted on your Server 2012 R2 domain controllers, and made a couple of those 2012 R2 DCs global catalog servers, you can get rid of the existing Server 2003 DCs.
Moving FSMO Roles 1
One of the advantages of moving Active Directory from Windows Server 2003 to Windows Server 2012 R2 is that you get to take advantage of all the new Windows PowerShell cmdlets.
Introducing new 2012 R2 domain controllers to a 2003 environment 1
Introducing new domain controllers running Windows Server 2012 R2 to a Windows Server 2003 environment is relatively straightforward.
Triaging Active Directory Migration
When thinking about Active Directory migration from Server 2003 to Server 2012 R2, it’s good to have a list of things to do and the order in which you should do them.
Understanding Active Directory Changes
Chances are, if you have an environment with a large number of servers running Windows Server 2003, you have domain controllers running Windows Server 2003. If you have domain controllers running Windows Server 2003, your domain and forest are likely to be at the Windows Server 2003 functional level.
Planning Active Directory Migration
There are two general strategies you can pursue when moving from an Active Directory Forest that has domain controllers running Windows Server 2003 to an Active Directory Forest with domain controllers running Windows Server 2012 R2.
Migration Test Environment – Part II
So what makes a good migration test environment?
Migration Test Environment – Part I
As someone wise once noted, when swinging through the trees, Tarzan didn’t let go of the last vine before he had grasped the next one.
Overview of Consolidation
When Windows Server 2003 was released, most Windows Server deployments were physical rather than virtual.
So why are so many people still using Windows Server 2003 anyway?

Thanks for the comments! What you are saying doesn't surprise me, but I may reference them in a future article on this issue.

Great products need great documentation

Alas the cost of creating great documentation is usually a lot higher than the revenue gained from publishing it as a separate product. That's why you rarely see great...

An advantage of classroom learning is that it gets people out of the work environment so that they can actually get some learning time. ;-)

Microsoft Delays Windows 10 Server Until 2016
January 30, 2015

It's depressing because there are many features that have been promoted, such as JIT admin, that aren't present in the current TP.

Also, put me down as a vote for...

Missing in Action: Windows 10 Server
January 22, 2015

Looking forward to seeing features like JIT administration - something that we won't be able to play with until we can run a domain at the vNext functional level.
