After an upgrade to 12.5.30 you may experience issues with PHP, because the Apache worker module may change and leave the PHP5 module de-activated. If you set it to worker MPM and activate the PHP5 module again, things will be as they used to be.
You will also likely run into issues with Fail2Ban. If this prevents an update, fully remove all fail2ban modules first (via SSH, use not only "yum remove fail2ban", but "yum remove fail2ban\*", else some fail2ban libraries will remain on the system), then do the upgrade, afterwards re-install fail2ban using "yum install fail2ban".
