Article Summary: This article addresses how to perform a server to server migration of the operating system
Issue:
This article is designed to provide a step by step walkthrough of the migration of a server running Windows Server 2008 R2 with the Active Directory Domain Services (ADDS) role installed and acting as a domain controller to as server running Windows Server 2012 R2. The migration includes migrating the Active Directory (AD) environment, Domain Naming System (DNS) and Dynamic Host Configuration Protocol (DHCP). The migration is designed to migrate everything with zero downtime in the environment allowing clients to continue to operate uninterrupted. The roles will be added and configured on to the server running Windows Server 2012 R2. The goal is to retire the server running Windows Server 2008 R2.
The current environment is configured as follows.
Hardware - Dell PowerEdge 1950
Operating System - Windows Server 2008 R2
Computer Name - W08R2-DC
Roles - ADDS, DNS, DHCP
IP Address - 192.168.0.1
Domain - domain.local
DHCP Scope - Client-Scope
Hardware - Dell PowerEdge R820
Operating System - Windows Server 2012 R2
Computer Name - W12R2-DC
IP Address - 192.168.0.2
This document can be used as a reference for performing a migration in a customer environment. Simply substitute the following information throughout the document.
W08R2-DC = customers' existing domain controller computer name
W08R2-DC IP address = customers' existing domain controller IP address
W08R2-DC DHCP scope = customers' existing DHCP scope

W12R2-DC IP address = customers' new server IP address
domain.local = customers' forest/domain name
