Server not using the latest kernel installed

I am running RHEL 7.3 I updated the /boot configuration based on one of the answers from here (Relocate /boot to the root partition). After that, I upgraded the kernel from kernel-3.10.0-514.el7.x86_64 to kernel-3.10.0-693.el7.x86_64. It is installed as per below: [root@qradar-hardened user]# rpm -qa | grep kernel kernel-3.10.0-693.el7.x86_64 kernel-3.10.0-514.el7.x86_64 kernel-tools-libs-3.10.0-514.el7.x86_64 kernel-tools-3.10.0-514.el7.x86_64 [root@qradar-hardened user]# However, after reboot, this change is not reflected. [root@qradar-hardened user]# uname -r 3.10.0-514.el7.x86_64 [root@qradar-hardened user]# I did the same without making changes to /boot and it works. So I think it has something to do with changing that. I followed this guide and changed the boot order to use this new kernel, but still does not work. Just need to make sure how can I make this to use the latest kernel.
