12.7 Windows NT4/2000 Troubleshooting Problems
12.7.2 Windows NT/2000 upgrade issues
The issues that will occur when upgrading to Windows NT and 2000 will be similar to the issues that occur when performing Windows 9x upgrades. As with Windows 9x, problems that occur during upgrades to Windows 2000 will either be hardware or software related, and sometimes there will be problems with both hardware and software. Before any upgrade is started, consult the Microsoft website to see if the hardware is compatible. Check with the manufacturer of the hardware components and software to see if they have any updated drivers that are necessary for the upgrade.

Also check that the hardware meets the minimum recommendations for the upgrade. Microsoft has a list of recommendations on its website for types of processors and the amount of RAM that is needed to run the selected operating system. It also includes recommendations for other hardware components.
