Finished upgrading all of the computers in my home from Fedora 30 to Fedora 31 over the long weekend. It was pretty uneventful!
My own laptop went smoothly, though slowly, because it has a mechanical hard drive. All of the packaged software upgraded correctly and with no intervention, including the stuff installed from RPMFusion. I had quite a bit of self-compiled stuff, mostly relating to sway, and some of that had to be re-linked.
