This worked for me on more then one occasion, but I don't pretend that it will
work for you or even not melt your computer into a pool of flaming goo.

Mandrake 9.2 upgrades cleanly older Mandrake systems (and at least on one
occasion, a RedHat 8.x) - just stick it into your coffee holder and
run /mnt/cdrom/live_update as root from X. it will present you with the
Mandrake 9.2 installation system and when choosing upgrade it will upgrade
the existing system to 9.2 while keeping all the configuration as is.
Note that you might need to edit your configuration files by hand or using the
supplied wizards to account for functionality changes with new versions of
some software packages (apache 1 to apache 2 for example). at then end it'll
require a quick reboot in order to load the new kernel so expect about 2
minutes down time.
Alternativly, if you feel intimidated by the above mentioned procedure (which
I do recommend you try on a non-production system first, just in case) you
can just get the SRPMS of the sofeware you want from the Mandrake 9.2 distro
(either from the commercial CDs or one of the many mirror sites) and rebuild
them on your system. assuming your system is already setup to compile C
programs or you can easily set it up to do so using your old Mandrake CD, it
should be fairly easy - you will probably need to upgrade a bit more packages
then what you though but RPM will prompt you nicely for what it needs. this
is a much lengthier process, but not the dependency hell people make of it
and it'll be less stressfull on your nerves then the full upgrade.

As always I'm available for questions and/or help in doing the actuall work
for a modest fee :-)
