How to upgrade to latest stable Kernel?

The latest stable version of Rockstor 3.8.16 uses Kernel 4.8.7.

Is there an easy way to upgrade the Kernel to its latest stable release (e.g. 4.9.2)?
I’m pretty sure there is nice howto’s available for Rockstor/CentOS.

Are you aware of running into problems upgrading Rockstor 3.8.16 to a newer Kernel version?

Thanks for commenting - regards,
