Hi,
you can do the following - shud work fine without any issues:
yum update yum ( get the latest version of yum )
yum update centos-release ( To update to latest release )
rpm --rebuilddb -vv ( not required - just for the heck )
yum update
That should upgrade all the packages ( if you see any error - u will have to do a bit of trouble shooting )
After update check kernel: yum list kernel
Update grub and reboot into new kernel. I upgraded from 4.1 to 4.4 on 2 servers and it went fine.
you use grub on s390 ?
