I cannot downgrade (without destroying a lot of other stuff).
Just got together with the team, CentOS gives too much issues with standard packages. Although I love RH and been using it since who knows when, I'm switching to a Ubuntu Server environment, because we simply do not have time to debug 3rd party stuff that works out of the box on any linux system, except CentOS (x64). I don't know what the CentOS team is up to, but the latest versions have been having terrible issues with upgrades and versions (PHP is a mess to name an example, having to use the remi repository to be up to date is simply for amateurs.) So after many, many years, they have lost me as a hard core user.
If I encounter any issue with the new attempt, I will let you know. You guys can close this thread. Do NOT use CentOS if you can avoid it.
Thank you so much for your support!
