Like its upstream source CEntOS provides a tightly coupled package set that enables you to concentrate on using the OS whatever you use it for instead of wasting time manually chasing kernel security updates, troubleshooting errors and performing more than the required amount of maintenance. So in essence you should not: either use CEntOS-5.8 or install CEntOS-6.3 and use the kernel it provides.

*That shouldn't stop you from tinkering though. You're always free to build or install a more recent kernel version. You'll learn from it and as the saying goes if you break things you get to keep the parts (and for future threads do list in which way you Frankensteined your machine should b0rkage occur).

No. With all due respect you're reasoning the other way around. Either these developers should seek to get their application approved for CEntOS-5.8 or CEntOS-6.3 or be taught about RHEL product updates and life cycles. The practice of applications keeping software or a whole OS captive, keeping them from having required bug fix and security updates applied (in order to remain eligible for support for example), is IMNSHO an abysmal one.

RHEL 5 Update 7 was released in June 2011 and there have been 5 kernel upgrades since its release and the last one was 2.6.18-274.18.1. Update 8 as released in February of this year and there have been 6 kernel upgrades bringing it up to 2.6.18-308.8.2. (By comparison RHEL 6 Update 3's kernel saw 4 updates, current being 2.6.32-279.5.2 IIGC.) So if I understand you correctly and you have not upgraded 5.7 to 5.8 then you're short of a total of 11 kernel updates. And the longer you choose to keep obsolete kernel versions the harder it will become to get up to date in an efficient way.

Take one CEntOS-5.7 machine and bring its kernel version up to 2.6.18-274.18.1. Then update it to 5.8 and follow the kernels upgrade path to 2.6.18-308.8.2. Then you can stay with CEntOS-5 until 2017, which marks the end of the regular life cycle (upstream extended support from 7 to 10 years).

* Again, yes you can try to transplant 6.3's 2.6.32-279.5.2, yes you can scour any 3rd party repo for newer kernels or build your own ones but such kludges are ill-supported by the community and IMHO for good reasons.
