It usually works for me without much fuss. If you'd like to be certain
you can try doing a test installation on the new server. Once
installed, take a peek at the kernel parameters. If you see anything
markedly different, just add a stanza to the old system with the
parameters from the test installation before shutting it down.

You may also want to peek at any kernel modules that you load for
things like CPU scaling or other machine specific features.
