A simple upgrade is somewhat risky because you are replacing almost
every component of the currently running system. It is very possible
that the terminal you are running the command in (unless you're on the
console) or the desktop could crash. Then you end up with a
half-upgraded system that might not function. The system-upgrade runs
offline with nothing else running so it's safe that way. Also,
system-upgrade sometimes has extra handling for certain situations. For
example, the upgrade to F32 required resetting all the modules.
I will do regular updates live (I have run into issues with that a
couple of times though), but for new releases I always use system-upgrade.
There is an option called "upgrade" under dnf system-upgrade.
However: https://fedoramagazine.org/upgrading-fedora-31-to-fedora-32/ does not mention it
and suggests using:
sudo dnf system-upgrade download --releasever=32
What is the difference?
Many thanks,
