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.
Decommission Vs Repurpose
One unusual problem that turns up when migration occurs, especially workloads have been moved off “bare metal” hardware and virtualized, is “what do we do with the bare metal hardware once the workload is migrated?”
Windows Server 2003 Migrations: Locally hosted or Cloud VMs?
When migrating workloads from Windows Server 2003 to Windows Server 2012 R2, should you deploy them locally as VMs on a virtualization host that you manage, or should you host them in the public cloud?
Department of Homeland Security issues alert about end of Windows Server 2003 support
US-CERT, the United States Computer Emergency Readiness Team has released an alert reminding people about the impending end of extended support for Windows Server 2003.
Physical or Virtual?
When planning the migration of workloads away from Windows Server 2003, you’ll need to choose whether those migrated workloads will be deployed on “bare metal hardware” or whether they will be virtualized.
Triaging Migration Workloads
Unless you’re already deeply into the migration process, it’s probable that your organization won’t have migrated all workloads from Windows Server 2003 to Windows Server 2012 R2 or another operating system by the time that the end of extended support date rolls around in July 2015.
Migrating your team’s skills – Part II
So you’re on the path to migrating from Windows Server 2003 to Windows Server 2012 R2 and know that you need to get your team skilled up so that they are knowledgeable about the new operating system.
Should you migrate Windows Server 2003 workloads to the public cloud?
Some who are planning their migration away from on premises Windows Server 2003 have wondered if instead of migrating to an on-premises hosted version of Windows Server 2012 R2, they should instead migrate their workloads to the public cloud.
Which version of Windows Server should your migration from Windows Server 2003 target?
When discussing migration away from Server 2003 with IT Pros, I occasionally get asked “well, what if we migrated to Windows Server 2008 R2 instead of Server 2012 or Server 2012 R2?”.
Should you hold off migrating from Windows Server 2003 until Server vNext is released?
Should you continue your migration to Windows Server 2012 R2 or hold off until vNext is released?
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.

What is the value of IT industry and/or Microsoft certifications?

Certifications provide a structure (and a reason) to learn a new technology. Not everyone has the inclination to wander through (for example) the AD FS or AD RMS documentation...

Microsoft layoffs impact Exchange technical writers - where now for documentation?
