moving IIS server from windows NT 4.0 to Windows 2000

Hi all,
Has anyone done migration of IIS server from Windows NT 4.0 to Windows 2000 Advanced server? I like to know the steps involved and complication that may occur during the process. Are there more than one way to do this?
Any help will be highly appreciated.
Thanks.
