The latest linux fedora distribution came out a few days ago.. and for once I actually missed the event.
So starting yesterday, I started the twice a year process of upgrading all of the linux fedora servers. It is getting better and better!
The first one went without error and completed within 15 minutes. The next two also went without issue and completed within 30 minutes.

The base process remains the same:
sudo dnf upgrade –refresh
sudo dnf install dnf-plugin-system-upgrade
sudo dnf system-upgrade download –releasever=31
sudo dnf system-upgrade reboot
sudo dnf system-upgrade clean

Since yesterday, 5 servers and 1 workstation have been upgraded and so far only one had boot grub issues. Those issues have been fixed.
