I have Linux 3.10.65 armv7l kernel on my industrial computer, need to upgrade it manually is it possible if it is, how?

CPU Quad-core ARM CortexTM-A7 Processor

OS Linux3.10

FLASH 8Gbytes EMMC

RAM 1GbytesDDR3

I am a linux user already but the kernel is too old than i used before and the Linux 3.10 kernel series reached end of life and it will no longer receive maintenance updates that patch critical security vulnerabilities. So I need to upgrade it.
