Unfortunately, there's not possibility in this specific situation to be able to update from 6.3 -> 6.8.
any such external specifications that insist you run an old obsolete operating system are inherently broken. I hope this server isn't connected to the internet, and isn't providing any services to untrusted users.
any RHEL/CentOS 6 compatible applications you have that work on 6.3 that won't work on 6.8 are broken.
* 6.8's kernel is is still 2.6.32, same as 6.3. * 6.8's glibc is still 2.12 * 6.8's php is still 5.3 * 6.8's mysql is still 5.1 * 6.8's postgresql is still 8.4 * 6.8's perl is still 5.10 * 6.8's python is still 2.6.6 * etc etc.
all of these components have security and bug fixes from later releases backported to them.
