[NTLUG:Discuss] upgrade kernel only?

[Steve Jackson]

Unfortunately, going from 2036 to 2216 isnt that easy.  To be able to
use the newer 22 kernels, you have to upgrade several parts of the
system (libararies, etc).  I would recommend backing up any config files
that you have, and doing a fresh install.  OTOH, it sounds like you have
a stable system, so the hassle of updating may not be worth the
performance increase on a machine that is depended upon in a production
environment.  Of course, you could always build a new machine and
replace the older one with it without any downtime (presuming you have
the resources to do that).
