Determining Implementation Methods
Windows 2000 Professional includes tools that provide you with the flexibility to choose a method of deployment that will best help you achieve your specific technical and business goals, and meet the needs of your network infrastructure.
Determining Your Installation Processes
There are two basic approaches to deploying Windows 2000 Professional to existing computers; the first is to upgrade the existing operating system, and the second is to run a "clean" installation.
Upgrade
Windows 2000 Professional Setup includes the ability to upgrade Windows 3.1, Windows 95, Windows 98, and Windows NT Workstation version 3.51 and version 4.0. After an upgrade the user's operating system settings, applications, and data are preserved.
Clean Installation
There are two methods of running setup using the clean installation method:
- The operating system is installed on a computer system with a newly formatted hard disk drive or
into a different directory from the existing operating system. After setup is complete, the user's data must
be restored and applications must be reinstalled. The operating system is copied using a third-party disk-image copying tool, along with
applications and settings, to the hard disk drive as part of a hard disk drive image. This is often
referred to as disk-image copying. After disk-image copying is completed, the user's data must be restored.
If you are deploying new computers, have them preconfigured and tested prior to deployment. This will remove any potential issues with hardware and configuration incompatibilities or discrepancies.
Minimizing the Costs of Implementation
You might determine that a Windows 2000 Professional deployment project is an opportune time to implement best management practices, taking advantage of the features of Windows 2000 Professional that enable improved management and lower total cost of ownership (TCO).
Using Disk-image Copying
If your existing environment has a standardized hardware base, then a clean install using disk-image copying is the recommended method to deploy Windows 2000 Professional. It can provide the most effective, lowest cost method to deploy a standardized image of Windows 2000 Professional and applications. In many cases, this method of deployment is cost-effective because it reduces the number of hours necessary to both install and configure the operating system and applications for each computer significantly. Disk-image copying allows the full desktop to be deployed in one pass: operating system, applications, and settings. In addition to this, planning and preparation for the installation process is reduced. Using disk-image copying ensures that each system has a standard directory structure, a best practice that typically enables ongoing change and configuration management. Backing up local end user data and settings is the most significant cost of using the disk-image copying method, and needs to be taken into consideration when evaluating this deployment method.
Windows 95 or Windows 98
Organizations with a Windows 95 or Windows 98 environment will find that a clean install is the most cost-effective method for deploying Windows 2000 Professional. A clean install increases the success rate of setup and reduces the complexity of your environment. A clean install eliminates the potential software configuration issues that often arise due to users installing software and making configuration changes over time. Customers with a well-managed, homogeneous Windows 95 or Windows 98 environment need to create a lab environment that will allow them to develop, test, evaluate, and refine an upgrade process that can then be implemented on production systems.You will also need to test your applications based on Windows 95 or Windows 98 and determine if there are any issues that need to be addressed. Create a plan for addressing these issues in the lab environment prior to rollout.

Windows NT Workstation 4.0 and Windows NT Workstation 3.51
If your existing environment consists of either Windows NT Workstation 4.0 or Windows NT Workstation 3.51, then upgrade is the most cost-effective method for deploying Windows 2000 Professional. However, if third-party network components, anti-virus programs, computer manufacturer developed utilities like power management utilities, or software digital video disc (DVD) decoders are installed on your clients, it might be necessary to perform a clean install. You might also develop a process to uninstall the components before installing Windows 2000 Professional.
