Hi, To upgrade from say 7.X to 8/9 is the best tactic just to upgrade the redhat-release package by hand and then rely on $releasever in yum.conf which I have. Is there anything magic I can add on the command line to overide the value $releasever obtained from the redhat-release package allowing me to miss that first step before running yum upgrade?
