I think they are simply suggesting the DNF upgrade option, which is shown here: https://fedoraproject.org/wiki/DNF_system_upgrade That page is currently showing instructions to upgrade to F27, which includes the line: sudo dnf system-upgrade download --refresh --releasever=27 So Matthew is noting that people have tested, and found it to work, if you run that "27" upgrade from an F25 system. You would simply follow the instructions just the same as somebody upgrading from F26 to F27. I run MD raid without using LVM, but note that the upgrade is not making changes to how the system is installed. It is really just doing a bunch of DNF upgrades to individual packages. It *is* a major change in that every package gets updated. That said, there are upgrades that introduce major changes. As systemd was being introduced there were upgrades that were more scary than normal. If the F25 to F26 transition is doing something to change how RAID+LVM is handled then hopefully somebody will jump in and give you a warning. As to the question of what to backup... Backup up your user date only if you know that you can redo all the config options if you are forced to fully reinstall. Backup everything if you want to make 100% sure that you save a copy of every little file that might have some change in it that you might want to look at later. -- Doug H. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
