You can upgrade your systems the same way as on plain Debian
systems. 'apt-get update ; apt-get upgrade' (or even better: use
aptitude).

The grml-related stuff:

There's a virtual package named 'grml' which was introduced with
grml 0.5 to make sure that an upgrade to a new release won't break
anything. Run 'apt-get update ; apt-get install grml' when a new
grml release is available and your grml packages will be up2date.

All grml-related packages start with name 'grml-'. (That's a
policy.) This allows you to do stuff like (untested command line,
just to get an idea):

# for package in `dpkg --get-selections|grep '^grml'` ; do echo $package hold | dpkg --set-selections ; done

This examples would put all grml packages to status hold.  Upgrades
won't affect grml related packages then.

Kernel:

Stable grml kernels can be upgraded through the grml repostory like
as normal packages.

Not yet officially released kernels - the beta-releases - can be
found at http://dufo.tugraz.at/~prokop/grml-kernel/  These are also
the ones used on grml-develreleases BTW.

And of course you can install and run kernels provided by Debian:

% apt-cache search linux image

Then install and use the one which corresponds best to the used
hardware.
