Brianjmurrell: In step 2, dnf update --refresh is it really necessary to upgrade every package on a system you are about to upgrade to new versions of those same packages anyway? I could certainly see wanting to update a subset of packages covering dnf and rpm perhaps but why do I need to update things like my desktop packages to latest on release N when I only going to turn around and update that N+1 right away?
Kparal (talk): The point is to update important system tools like dnf, rpm, systemd, dracut, grub, etc, because there might be (and sometimes really is) some bug that badly interferes with the upgrade procedure and an update fixes it. So if you haven't updated in a long time, this command makes sure you have it fixed before you attempt to upgrade. If you use and update your system regularly, the amount of updates should be quite small, even though it includes all packages.
