This document outlines a plan to migrate components from a Windows Server 2003 environment to Windows Server 2008 R2. It discusses migrating Active Directory, DNS, enterprise CA/PKI, RADIUS (IAS to NPS), and DHCP while maintaining existing configurations, users, and IP settings. The plan is to use best practices to move servers and services to new 64-bit hardware without disrupting clients.

2.  WS2K3  WS2K8 R2 Components Migration
 Benefits & Requirements
 Migration Scenarios
 Migration Plan
 Q/A
 New Feature of WS 2K8 R2

3. / DHCP / LDAP / DHCP / LDAP
RADIUS (IAS) NPS,NAP
Branch Domain Controllers RODC
WPA2 Enterprise

4.  Use New Features of WS2K8r2 with Win7 Together
 Use New Policy on WS2K8r2 e.g. FW Policy / PKI Policy
 Replace New Server HW with 64-Bit
 Move Upgrade/Migrate Windows Server OS to x64
 Maintained the NTDS.DIT & FSMO Placement
 Maintained the Existing AD / DNS / GPOs & OUs Structure
 Maintained the Existing AD Sites Topology / AD Replication
 Maintained All SID (Security ID) of Users Profiles & Desktop
 Maintained the TCP/IP Settings of Domain Controllers
 Maintained All DHCP Config e.g. Reserve Scope / DHCP IP Scope
 Maintained Browser Settings for Web Clents

5.  AD/DNS Migration (Root or Child Domain)
 Enterprise CA / PKI Migration
 RADIUS (IAS) Migration to NPS of WS 2K8 R2
 DHCP Migration & TCP/IP Setting
 Source & Destination Server/OS Migration
 Migration Plan

6. AD/DNS Migration scenarios
 Use Best Practice to migrate AD
 Migrate and maintained
the Existing AD Configuration
 Move Existing with All AD Structure
to New HW on 64-bit
 Migrate DNS/Zone Configuration
of Existing Domains
 Migrate Server Name & IP Setting
of Domain Controllers

7. Enterprise CA Migration scenario
 Use Best Practice to Migrate CA & PKI
 Migrate Existing CA with Same Key
 To Use New Version CA Template
 To Configure Auto Enroll Policy
 Modify Expiration date Expansion

8. RADIUS Migration scenarios
Use Best Practice to migrate and maintained
the existing configuration of IAS to NPS
 Export RADIUS Configuration
 Enable NPS on WS2K8 r2
 Move RADIUS Config to New WS2K8 r2 NPS
 Migration Scenarios support
ws2k8 x86/x64 to ws2K8r2 x64

9.  New DHCP Services on WS 2K8 r2 is enable
 Migration All Existing DHCP Data from WS2K3
 Migration All Existing DHCP All Reserve Scope
 Maintained Existing DHCP Configuration
 All Clients will use it old IP Setting Leased
 DHCP Services not impact to All Clients on LAN

10. When completed the migration process
 The DCs will use it own IP Address, TCP/IP
setting will be same as existing configuration.
 Server Name of DCs will be same as its old
 DNS Services & DNS zone will migrate &
maintained the existing Configuration
 Void Clients impact, All Servers IP Not change
 Not Impact to Hard-Config IP Address use
