    Very well, seems to have hit every point but one. What happens if the install fails at step 10 ??

    • Ravi Saive says:

      @HJWaggoner,

      I am 100% sure that the upgrade won’t fail, as me personally upgraded my two RHEL 7.x server to RHEL 8 and upgrades went smoothly without any issues..
