No. First of all, not everyone would consider Windows an "upgrade." Secondly, Windows does not support migrating a Windows system, so you have to erase the hard drive and do a clean install.
An operating system is the software that runs your machine such as windows / linux / mac. So if you were to upgrade it you are simply upgrading to a newer version
Windows XP is not in the direct upgrade path of Red Hat Linux 8.0. If you want to install Windows XP on a computer / server with RHL, you need to check the hardware specifications to see if Windows XP supports it.
It Depends What You Want To Upgrade, If you wanted to upgrade from say windows vista to windows 7 then YES you would need a disk, however if you were downloading the software to upgrade then you could put it onto a USB flash drive and install that way, some OS Like LINUX provide a installer which you can download from their website

Windows XP Professional is an upgrade to Windows 2000 Professional. Windows Server 2003 is an upgrade to Windows 2000 Server.
Windows 10 is an upgrade of earlier Windows versions like Windows 7 and 8.1, offering improved security, speed, and modern features. Later, Windows 11 upgraded Windows 10 with a refreshed design, better performance, and new tools. Each version of Windows builds on the previous one to enhance user experience and productivity.
Two operating systems are; Windows, and Linux.
Linux is considered to be more secure than Windows.
Vista Home Premium : Not Linux! Get linux! Vista Business : Not Linux! Get linux!
There is no such thing as "Windows Linux." Linux is not a version of Windows and has nothing at all to do with Windows. They are two totally completely different operating systems made by completely different people.
Windows is better for desktop computers. Linux is better for servers.
