yep, there are also prepared scripts in $SGE_ROOT/util/upgrade_modules/ called
"save_sge_config.sh" and "load_sge_config.sh" .
While the "save_sge_config.sh" will do the correct thing, the
"load_sge_config.sh" is meant to be used in an empty SGE installation. It might
work in some cases even by overriding the previous setting, but if you have
e.g. mutal settings in two queues for subordination of the other queue, you
first have to remove this subordination in one queue before you can remove the
other queue at all. And the "load_sge_config.sh" isn't so sophisticated to
cover these cases.
