At the end of this module, students will be able to: „# Plan the deployment of their migration strategy. „# Identify the planning documents to create. „# Choose a method for deploying Microsoft ® Windows ® 2000. „# Create the test and pilot plans for their migration strategy. „# Define the steps to ensure a smooth transition from pilot to production. 0DWHULDOV#DQG#3UHSDUDWLRQ# This section provides you with the required materials and preparation tasks that are needed to teach this module. 5HTXLUHG#0DWHULDOV# To teach this module, you need the following materials: „# Microsoft PowerPoint ® file 2010A_08.ppt „# Module 8, “Planning to Deploy a Migration Strategy” 3UHSDUDWLRQ#7DVNV# To prepare for this module, you should: „# Read all of the materials for this module. „# Complete the labs. „# Read all of the delivery tips. „# Read the technical white paper, “Automating the Windows 2000 Upgrade,” on the Student Materials compact disc. „# Read the following chapters from the Windows 2000 Server Deployment Planning Guide on the Student Materials compact disc: • Chapter 4, Building a Windows 2000 Test Lab • Chapter 5, Conducting Your Windows 2000 Pilot • Chapter 13, Automating Server Upgrade and Installation • Chapter 14, Using Systems Management Server to Deploy Windows 2000 • Chapter 21, Testing Applications for Compatibility with Windows 2000 „# Microsoft Official Curriculum (MOC) course 1517, Principles of Infrastructure Deployment, is a good source of information for general deployment guidelines and Microsoft Solutions Framework processes discussed specifically in this module and used throughout this course. „# Read the Appendix, "Mitigating and Managing Risk During Migration." 3UHVHQWDWLRQ=# 48#0LQXWHV# # /DEV=# 63#0LQXWHV# LY##0RGXOH#;=#3ODQQLQJ#WR#'HSOR\#D#0LJUDWLRQ#6WUDWHJ\# 0RGXOH#6WUDWHJ\# This module shifts away from the technical details of migration to the soft skills components of project planning and management. Because many of the students we expect to see in planning courses are support professionals who may lack project-planning skills, this module is important in bridging the skills gap. This module provides a very brief look at a few key deployment project components. Explain to students why this information is important and engage the more experienced consultants in discussion of their planning methods so that the less experienced students can learn from them. If your class is filled with experienced consultants who prefer to follow their own planning or project framework, you might want to skim certain sections and spend more time on the technical components, such as choosing an installation strategy. Use the following strategy to present this module: „# Creating a Migration Project Plan Explain the steps for creating a project plan. Define vision and scope, and speak about how these concepts help in guiding the planning process. Explain the various roles that make up a successful project team. Describe the components of a functional specification document. „# Creating Project Planning Documents Discuss the administrative and deployment planning documents to be created. Emphasize that administrative documents help you identify goals and define objectives. „# Choosing an Installation Strategy Discuss the different methods of running an automated installation of Windows 2000 and when to use each one. „# Testing the Migration Plan Emphasize that testing is a way to reduce migration risk. Emphasize how the test environment differs for different migration paths. „# Piloting the Migration Plan Explain that a pilot needs to be performed before beginning the actual migration. Explain that the objective of the pilot is to provide a structured environment for planning, designing, and deploying Windows 2000 technologies. Describe the pre-pilot tasks to be performed. Discuss the pilot project phases. „# Planning for a Smooth Transition to Windows 2000 Describe the steps that ensure a successful transition to Windows 2000. Emphasize that students should not perform migration operations that affect users in the middle of an important business project or critical time of year, such as tax season. „# Best Practices Describe the best practices for deploying the chosen migration strategy. # 0RGXOH#;=#3ODQQLQJ#WR#'HSOR\#D#0LJUDWLRQ#6WUDWHJ\##Y# In the labs for this module, students make design decisions regarding the development of a test plan for an early phase of migration. In Lab A, students address design decisions for an upgrade test plan, whereas in Lab B, they address the design decisions for a domain restructure test plan. The design decisions addressed in the two different labs mirror one another. The main difference between the labs is the test cases–the issues that need to be validated in this phase of testing for a particular migration path. Students are not expected to complete both labs. Work with the students to determine which lab is of greater interest to students based on the migration that they will perform in their organization. If you have customized this course, the lab delivered for this module should reflect the migration path content of the custom course materials. If time permits and students are new to planning deployments, consider presenting the Appendix, "Mitigating and Managing Risk During Migration." This appendix can be placed either before or after Module 8. The lab for the appendix is particularly useful for students new to the architect role because it walks students through each step in developing a risk plan, a deployment document that is key to migration success. # 0RGXOH#;=#3ODQQLQJ#WR#'HSOR\#D#0LJUDWLRQ#6WUDWHJ\##4# 2YHUYLHZ# „ &UHDWLQJ#D#0LJUDWLRQ#3URMHFW#3ODQ „ &UHDWLQJ#3URMHFW#3ODQQLQJ#'RFXPHQWV „ &KRRVLQJ#DQ#,QVWDOODWLRQ#6WUDWHJ\ „ 7HVWLQJ#WKH#0LJUDWLRQ#3ODQ „ 3LORWLQJ#WKH#0LJUDWLRQ#3ODQ „ 3ODQQLQJ#IRU#D#6PRRWK#7UDQVLWLRQ#WR#:LQGRZV#5333 „ %HVW#3UDFWLFHV Designing a Microsoft ® Windows ® 2000 migration strategy involves selecting a migration path to Windows 2000, developing an upgrade or restructuring strategy, and ensuring continued productivity during a domain upgrade or restructure by managing and mitigating risks of a production environment. Before implementing your migration strategy, you need to develop a plan to deploy it. At the end of this module, you will be able to: „# Plan the deployment of your migration strategy. „# Identify the planning documents to create. „# Choose a method for deploying Windows 2000. „# Create the test and pilot plans for your migration strategy. „# Define the steps to ensure a smooth transition from pilot to production.

Without a thoroughly-planned migration strategy and a project plan, migration seems overwhelmingly large and complex, the project would most likely fail to deliver its key business value, goals and vision would conflict between Information Technology (IT) and executive management, and the project lacks a certain integrity. Your overall project plan includes various aspects of both your business and your technical network infrastructure. When creating a project plan, you must: „# Define your migration vision and scope. „# Identify personnel requirements and organize your migration teams. „# Create a functional specification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„ 9LVLRQ z ,V#DQ#XQERXQGHG#YLHZ# RI#WKH#IXWXUH#QHWZRUN z (VWDEOLVKHV#ERWK#ORQJ0 WHUP#DQG#VKRUW0WHUP# JRDOV „ 6FRSH z 3URYLGHV#WKH#ERXQGV#IRU# WKH#PLJUDWLRQ#SURMHFW z 'LIIHUHQWLDWHV#EHWZHHQ# ZKDW#WKH#PLJUDWLRQ#PXVW# DFFRPSOLVK#DQG#ZKDW#LV# QRQ0HVVHQWLDO# Executive Summary Position Problem Statement Vision Project Scope Project Assumptions Project Requirements Project Success Factors Project Team Structure Roles and Responsibilities Project Schedule Project Risk Assessment Document Sign off Vision/Scope Document 9LVLRQ#6WDWHPHQW# The migration vision is an unbounded view of the future network. It establishes both long-term and short-term goals. You can use it to inspire the team for the long-term success of the migration. It also helps establish shorter-range objectives. Both in turn lead to high-quality action. A vision statement might read like the following: The vision of this project is to deploy a cost-effective, high-value architecture that improves reliability, reduces the total cost of ownership, and provides for end-to-end management of all systems in the enterprise. Each organization has its own business vision. By collecting information on the vision or goals of the organization and keeping these goals in mind while creating the migration vision, you help ensure that the migration project aligns with the long-term vision of the organization. 6FRSH#6WDWHPHQW# Migration scope provides the bounds for the migration project. It may prioritize the Windows 2000 components that must be in place first to meet the most pressing business needs. It differentiates between what the migration must accomplish and what is non-essential. A scope statement might read like the following: The scope of this pilot is to investigate and test the features and functionality of Windows 2000. All departments will gain experience and interest so that they are prepared for the future network. 6OLGH#2EMHFWLYH# 7R#GHILQH#PLJUDWLRQ#YLVLRQ# DQG#VFRSH1# /HDG0LQ# $#PLJUDWLRQ#YLVLRQ#VWDWHPHQW# VKRXOG#DUWLFXODWH#WKH#NH\# EXVLQHVV#MXVWLILFDWLRQ#IRU#WKH# PLJUDWLRQ#WR#:LQGRZV#5333# $FWLYH#'LUHFWRU\1#7KH# PLJUDWLRQ#VFRSH#HVWDEOLVKHV# WKH#ERXQGDULHV#IRU#WKH# PLJUDWLRQ#E\#GHILQLQJ#ZKDW# WKH#SURMHFW#VHHNV#WR# DFFRPSOLVK1# 8VH#WKH#VOLGH#WR#GHILQH# PLJUDWLRQ#YLVLRQ#DQG#VFRSH1# # .H\#3RLQWV# 9LVLRQ#LV#WKH#LGHDOL]HG#YLHZ# RI#WKH#IXWXUH#QHWZRUN1# # 7KH#VFRSH#SURYLGHV#UHDOLVP# WR#WKH#YLVLRQ1#,W#GHILQHV#ZKDW# WKH#PLJUDWLRQ#SURMHFW#LV#QRW# H[SHFWHG#WR#DFFRPSOLVK1# 7# # 0RGXOH#;=#3ODQQLQJ#WR#'HSOR\#D#0LJUDWLRQ#6WUDWHJ\# 9LVLRQ26FRSH#'RFXPHQW# During the migration, the vision/scope document provides the data necessary to make trade-off decisions about what features can be sacrificed if the schedule becomes impossibly tight or if resources become scarce.
