Trang 2Before you attempt to upgrade Windows 2000 Professional, you need to understand the difference between an upgrade and a clean installation If your previous operating system can be upgraded to Win-dows 2000 Professional and you want to retain your system settings, then you choose to perform an upgrade If your operating system does not sup-port a Windows 2000 upgrade or if you want to start from scratch, then you choose to perform a clean installation Client upgrade paths and requirements are used to determine if your operating system can be upgraded to Windows 2000 Professional In order to upgrade, you must be running Windows 9x or Windows NT 3.51 or 4, and your hardware must meet the minimum requirements This chapter covers the requirements for upgrading to Windows 2000 Professional.
You also should consider possible upgrade problems or known issues This is especially important if you are upgrading from Windows 9x, because the upgrading process is not as smooth as it is when you are start-ing from a Windows NT system An example of an upgrade issue is lack
of support in Windows 2000 for applications or utilities that use virtual device drivers You’ll find a discussion of these issues in this chapter.There are several tasks you should perform to prepare your computer before you start the upgrade process This chapter provides an upgrade checklist to help you plan your upgrade strategy Some of the items in the upgrade checklist include deleting any unnecessary files or applications and taking an inventory of your computer’s configuration
Finally, after you’ve made your preparations, you are ready for the big moment Here, you will learn about all of the steps involved in the Win-dows 2000 upgrade process
Trang 3Deciding Whether to Upgrade 99
Upgrade packs are used to make any changes to your Windows 9x or Windows NT applications that are required to make the application work properly in Windows 2000 The final section of this chapter describes how
to apply upgrade packs
The upgrade process for Windows 2000 Professional and Server is extremely similar The major differences involve the client upgrade paths and hardware requirements
Deciding Whether to Upgrade
An upgrade allows you to preserve existing settings A clean install places Windows 2000 in a new folder After a fresh install, you need to rein-stall all of your applications and reset your preferences
You should perform an upgrade if the following conditions are true:
You are running Windows 9x or Windows NT Workstation 3.51 or 4
You want to keep your existing applications and preferences
You want to preserve any local users and groups you’ve created under Windows NT
You want to upgrade your current operating system with the dows 2000 operating system
Win-You should perform a clean install if any of the following conditions are true:
There is no operating system currently installed
You have an operating system installed that does not support an upgrade to Windows 2000 (such as DOS or Windows 3.x)
You want to start from scratch, without keeping any existing preferences
You want to be able to dual-boot between Windows 2000 and your previous operating system
Performing a clean install and dual-booting are covered in detail in ter 1, “Getting Started with Windows 2000 Professional.”

Preparing to Upgrade to Windows 2000
Win- Use an upgrade checklist to plan for the upgrade
These preparations are discussed in detail in the following sections
Client Upgrade Paths and Requirements
In order to upgrade to Windows 2000 Professional, you must follow a ticular path Only the following operating systems can be directly upgraded
par-to Windows 2000 Professional:
Windows 95 (all releases)
Windows 98 (all releases)
Win- Apply update packs to installed software applications
Prepare a computer to meet upgrade requirements
Trang 5Preparing to Upgrade to Windows 2000 Professional 101
There is no upgrade path from Windows NT Server to Windows 2000 Professional.
If you are running a version of Windows NT Workstation prior to 3.51, you first need to upgrade to Windows NT Workstation 3.51 or Windows NT Workstation 4 Then you can upgrade to Windows 2000 Professional You cannot upgrade to Windows 2000 Professional from any version of Win-dows NT Server
The hardware requirements for upgrading are the same as those for a clean installation In order to upgrade to Windows 2000 Professional, your computer hardware must meet the following requirements:
Pentium 133MHz or higher processor
64MB of RAM (more memory is recommended)
2GB hard drive with at least 650MB of free disk space
VGA or better resolution monitorAlong with meeting these requirements, your hardware should be listed
on the Hardware Compatibility List (HCL) See Chapter 1 for more mation about the HCL
infor-The hardware requirements listed here were those specified at the time this book was published Check Microsoft’s Web site at http://www.microsoft.com/ windows2000/upgrade/ for the most current information.
The upgrade to Windows 2000 Professional from Windows NT is a smoother process than it is from Windows 9x This is because the Windows NT and Windows 2000 structures have more in common than the Windows 9x
and Windows 2000 structures do Therefore, upgrading from Windows 9x
requires more planning and testing than upgrading from Windows NT
Trang 6102 Chapter 3 Upgrading to Windows 2000 Professional
Compatibility Problems
To assist you in the upgrade process, the Windows 2000 Setup program vides a “report-only” mode, which generates compatibility reports and stores them in a central location You can then analyze these reports to deter-mine whether your hardware or software applications port properly from Windows 9x to Windows 2000 Professional
pro-You can generate the Windows 2000 compatibility report in three ways:
Run Winnt32 /checkupgradeonly, which will launch the Windows 2000 Setup program, but will only run enough of the setup procedure to gen-erate the compatibility report
Run the Chkupgrd.exe program This program can be downloaded from http://www.microsoft.com/windows/downloads/
Unsupported Options
Although Windows 9x can be upgraded to Windows 2000 Professional, you should be aware that the following options are not supported through the upgrade process:
Applications that use file-system filters, such as third-party anti-virus ware and disk-quota management software These types of file-system fil-ters won’t work under Windows 2000 You should contact vendors who use file-system filters for upgraded software supported by Windows 2000 Professional
soft-Any custom power-management solutions or tools Custom management solutions are no longer used, because these features are added through Windows 2000 Advanced Configuration and Power Inter-face (ACPI) and Advanced Power Management (APM) You should remove
Trang 7power-Preparing to Upgrade to Windows 2000 Professional 103
any custom power-management solutions or tools prior to running the upgrade process (The ACPI and APM are covered in Chapter 4, “Con-figuring the Windows 2000 Environment.”)
Any custom Plug-and-Play solutions Custom Plug-and-Play solutions are no longer used, because Windows 2000 has a full set of Plug-and-Play features You should remove any custom Plug-and-Play solutions before starting the upgrade process
Third-party applications for Windows 9x that support compressed drives, disk defragmenters, and disk utilities These are not supported
by Windows 2000 because it offers native support for disk compression and disk defragmentation (which are discussed in Chapter 9, “Managing Disks”) If you want to use third-party utilities, you should contact the vendor to get an upgrade of your application that has been written spe-cifically for Windows 2000 If the application can’t be upgraded to a Win-dows 2000–specific version, you should remove the utility prior to running the upgrade process
Any applications or utilities that use virtual device drivers (VxDs) or 386 drivers Older 16-bit drivers for Windows 9x were based on VxDs VxD drivers are not compatible with the Windows 2000 operating system You can determine if you are using these drivers by checking the [386Enh] sec-tion of the System.ini file Some device drivers use VxDs to provide property pages in property dialog boxes If you want to continue to use these applications or utilities, you should contact the vendor to get an upgrade of your application or utility that has been written specifically for Windows 2000
An Upgrade Checklist
Once you have made the decision to upgrade, you should develop a plan of attack The following upgrade checklist (valid for upgrading from both Win-dows 9x and NT) will help you plan and implement a successful upgrade strategy
Back up all of your data and configuration files and verify that you can successfully restore your backup Before you make any major changes
to your computer’s configuration, you should back up your data and configuration files Chances are if you have a valid backup, you won’t have any problems Chances are if you don’t have a valid backup, you will have problems
Trang 8104 Chapter 3 Upgrading to Windows 2000 Professional
Delete any unnecessary files or applications, and clean up any gram groups or program items you don’t use Theoretically, you want
pro-to delete all of the junk on your computer before you upgrade Think
of this as the spring-cleaning step
Perform a disk scan, a current virus scan, and defragmentation These are also similar to spring-cleaning chores This step just prepares your drive for the upgrade You should verify that there are no problems with your drive prior to the upgrade
Uncompress any partitions that have been compressed with DriveSpace or DoubleSpace You cannot upgrade partitions that are currently compressed
Verify that your computer meets the requirements for an upgrade Be sure that your computer meets the minimum hardware requirements for Windows 2000 Professional and that all of your hardware is on the HCL
Take an inventory of your current configuration This inventory should include documentation of your current network configuration, the applications that are installed, the hardware items and their con-figuration, the services that are running, and any profile and policy settings
Perform the upgrade In this step, you upgrade from your previous operating system to Windows 2000 Professional
Verify your configuration After Windows 2000 Professional has been installed, use your inventory to verify that the upgrade was successful
Performing the Windows 2000 Upgrade
As you would expect, the process of upgrading to Windows 2000 is much simpler than performing a clean installation (as we did in Chapter 1)
You pick the system from which you are upgrading, then follow the Setup Wizard’s instructions to provide the information the Setup program needs
The final steps in the upgrade process are automatic

Now you can just sit back and relax while the Setup program performs the rest of the upgrade automatically When the process is complete, Win-dows 2000 Professional will be installed on your computer At this point, it’s
a good idea to verify that everything was upgraded properly Using the tory you made before upgrading (see the “Upgrade Checklist” section earlier
inven-in the chapter), check that your hardware and software has made it through the transition and are working properly
Exercise 3.1 shows the steps for upgrading to Windows 2000 Professional
To set up your computer to be used for the exercises in this book, you installed Windows 2000 Professional from scratch in Chapter 1 You would follow the steps in Exercise 3.1 if you were upgrading from your current operating system, and you had not performed the clean install procedure outlined in Exercise 1.1
