Question Windows 11 upgrade

Simple answer is no, though you're advised to reinstall Windows 11 after you've upgraded to Windows 11 using the internal upgrade path to root out any internal corruptions during the upgrade process.

i.e, backup all mission critical data, recreate your bootable USB installer for Windows 11, disconnect all drive except for the one you wish to install the OS onto, format the OS drive, install Windows 11 in offline mode, install all relevant drivers in an elevated command while in offline mode, then connect to the internet to update the OS.
