Everything went on flawless. The upgrade even updated Nvidia drivers from Livna.
sudo yum update rpm sudo yum -y update
This command brought in about 1 Gb of updates.
sudo yum clean all
Reboot after this step has completed (needed only if your kernel version was outdated).
sudo yum -y install preupgrade sudo preupgrade
Will repeat for my Acer Aspire 6930 monitor during the nearest week-end.
