But I couldn't swear to that. If you just run "yum upgrade" or "yum update" (they behave the same by default), that's not what happens. To achieve that, you have to: yum --downloadonly upgrade telinit 3 yum -C upgrade On the other hand, preupgrade does drop you out of the running system, it does the upgrade in an Anaconda environment.
