Migrating successfully from Windows NT 4.0 to Windows 2000 requires in-depth planning based on careful analysis of your current infrastructure. The overall migration strategy will include several phases and mini-plans. The following are the phases that an enterprise must complete to successfully develop a Windows 2000 Active Directory migration strategy: 1. Design the required Active Directory forest. The Active Directory design identifies the migration project’s end goal, the ideal domain infrastructure for an organization. This phase involves designing an Active Directory structure that suits your business needs. For information on designing Windows 2000 Active Directory, see course 1561B, Designing a Microsoft Windows 2000 Directory Services Infrastructure. 2. Choose a migration path. This phase involves carefully comparing your business or migration goals with the capabilities of each migration path to select a path that meets your needs. The migration path that you choose will affect the remainder of your migration planning. 3. Develop a domain upgrade or a restructure strategy. After you have chosen a migration path, you can begin planning for the actual upgrade or restructure process. Within the overall migration strategy, you will define the steps that you will perform to achieve your desired Active Directory structure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lan deployment of migration strategy. The final phase of the planning process is the development of a deployment plan. The deployment plan details the steps necessary to implement the migration strategy. 7# # 0RGXOH#4=#,QWURGXFWLRQ#WR#'HYHORSLQJ#D#0LJUDWLRQ#6WUDWHJ\# 8SJUDGLQJ#9HUVXV#5HVWUXFWXULQJ# Domain Mi g ration Kerberos Windows 2000 OU OU OU OU OU OU Kerberos Windows 2000 Domain Upgrade Domain Restructure Windows NT 4 1 1 2 2 2 2 3 3 3 3 Up g rade Up g rade Up g rade ƒ Maintains current domain model ƒ Retains most of the system settings, preferences, and application installations ƒ Maintains current domain model ƒ Retains most of the system settings, preferences, and application installations Restructure Restructure Restructure ƒ Results in fewer, larger domains ƒ May reduce administrative overhead ƒ Results in fewer, larger domains ƒ May reduce administrative overhead If you assume that the pre-migration environment is the existing Windows NT 4.0 environment, the whole process of migration involves moving from that environment to Windows 2000 Active Directory. Performing a Windows 2000 domain migration is a very flexible process. Some organizations may only upgrade, or upgrade first and then restructure second. Still others may restructure from the start. The following are two approaches for achieving migration from Windows NT 4.0 to the desired Active Directory infrastructure: „# Domain upgrade. Sometimes referred to as an in-place upgrade or just upgrade, this is the process of upgrading the primary domain controller (PDC) and the backup domain controllers (BDCs) of a Windows NT 4.0 domain from Windows NT 4.0 to Windows 2000. Domain upgrade is a process designed to maintain as much of your current environment as possible. Upgrade may represent the easiest, lowest-risk migration route because it retains most of your system settings, preferences, and network service configurations. „# Domain restructure. Domain restructure is a process that enables you to redesign the domain structure according to the needs of your organization. Although a domain restructure can result in any number of different outcomes, it typically reorganizes your current structure into fewer, larger domains. You accomplish restructuring in Windows 2000 by moving security principles between domains. This allows an organization to first design an ideal Active Directory forest, and then populate it with users, groups, and computers. For example, you can convert a typical Windows NT multi- master domain model into a less complicated, single Active Directory domain in Windows 2000. Restructuring the domain results in reduced administrative overhead by reducing the number of domains and trusts that require administration and improving overall manageability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„ 3ODQQLQJ z ,V#DQ#RSSRUWXQLW\#WR#DOLJQ#,7#JRDOV#ZLWK#EXVLQHVV#JRDOV z +HOSV#GHWHFW#KRZ#D#FKDQJH#WR#RQH#DUHD#RI#WKH#HQWHUSULVH#ZLOO# LPSDFW#RWKHUV z ,GHQWLILHV#RSSRUWXQLWLHV#WR#DGG#YDOXH#WR#WKH#EXVLQHVV z $OORZV#WHFKQRORJ\#WR#EH#LPSOHPHQWHG#LQ#D#SURDFWLYH/# FRRUGLQDWHG/#DQG#IRFXVHG##PDQQHU z 0DNHV#HIILFLHQFLHV#SRVVLEOH z 5HGXFHV#WKH#FRPSOH[LW\#RI#PLJUDWLRQ Thoroughly planning your migration is critical to its success. In the planning phase, a project team documents and analyzes the current network environment of the organization. The team also measures the gap between the current environment and the goals for the future, and it defines the steps to achieve those results. Having a thorough plan allows the project team to concentrate on the migration essentials and provide results that can be implemented effectively. Planning: „# Is an opportunity to align information technology (IT) goals with business goals, enhance core business processes, or provide competitive advantages in the marketplace. „# Helps detect how a change to one area of the enterprise will impact others. „# Identifies opportunities to add value to the business side of the organization by applying technology in an innovative way. „# Allows technology to be implemented in a proactive, coordinated, and focused manner based on business strategy. „# Makes efficiencies possible, such as eliminating duplication of effort and reusing and leveraging IT investments and resources. „# Reduces the complexity of migration and the risks that change introduces. 6OLGH#2EMHFWLYH# 7R#H[SODLQ#ZK\#SODQQLQJ#LV# LPSRUWDQW1# /HDG0LQ# +DYLQJ#D#WKRURXJK#SODQ# DOORZV#WKH#SURMHFW#WHDP#WR# FRQFHQWUDWH#RQ#WKH#PLJUDWLRQ# HVVHQWLDOV#DQG#SURYLGH# UHVXOWV#WKDW#FDQ#EH# LPSOHPHQWHG#HIIHFWLYHO\1# <RX#VKRXOG#HPSKDVL]H# WKURXJKRXW#WKH#FRXUVH#WKDW# PRYLQJ#WR#:LQGRZV#5333# UHTXLUHV#D#VKLIW#LQ#WKH#ZD\# WKDW#SHRSOH#WKLQN#DERXW# GRPDLQV#DQG#GRPDLQ# DGPLQLVWUDWLRQ1# 9# # 0RGXOH#4=#,QWURGXFWLRQ#WR#'HYHORSLQJ#D#0LJUDWLRQ#6WUDWHJ\# 5HYLHZ# „ ,QWURGXFWLRQ#WR#'HYHORSLQJ#D#0LJUDWLRQ#6WUDWHJ\ „ 8SJUDGLQJ#9HUVXV#5HVWUXFWXULQJ „ 7KH#,PSRUWDQFH#RI#3ODQQLQJ 1. What are the phases that an enterprise must complete to successfully develop a Windows 2000 Active Directory migration strategy? Designing the required Active Directory forest, choosing a migration path, developing a domain upgrade or a restructure strategy, and planning deployment of the migration strategy. 2. Explain the difference between a domain upgrade and a domain restructure. A domain upgrade is the process of upgrading the Windows NT 4.0 PDC and the BDCs of a domain to Windows 2000 Server. A domain restructure, alternatively, is a redesign of the existing domain structure, which usually results in fewer, larger domains. 6OLGH#2EMHFWLYH# 7R#UHLQIRUFH#PRGXOH# REMHFWLYHV#E\#UHYLHZLQJ#NH\# SRLQWV1# /HDG0LQ# 7KH#UHYLHZ#TXHVWLRQV#FRYHU# VRPH#RI#WKH#NH\#FRQFHSWV# WDXJKW#LQ#WKH#PRGXOH1# . following strategy to present this module: „# Introduction to Developing a Migration Strategy Describe the four phases of domain migration planning.
