upgrade 12.04->14.04

[Saqman2060]

Yes, you can upgrade the kernel in 12.04 to latest. You can either install a new one from www.kernel.org or upgrade the kernel from the repositories. The last option will be more compatible. 

If it does not work then you can always go back to the previous kernel. 

Upgrading the entire system will upgrade all the software too and will have a completely new system.

As far as I know all the previous kernels will be uninstalled, as will
be the 12.04 one that you are running when you start the upgrade.  You
will be left with just the latest 14.04 kernel.  I don't know whether
kernels from 12.04 would run under 14.04, I think probably not.
