You may backup configure files via shell script, rather than "rpm -e ...", I did not see the necessary to previous uninstallation within %pre section.
Section %prerm of older relase will be operated when you upgrade your package.... Where you can do what you want.

Hi,
I have a question what about running 'rpm' command in the script of %pre.
Now, I need create a RPM package to upgrade the old version of our product to newest version. At first, we should backup old configuration and uninstall old version of our product. so, I write the script in %pre to run 'rpm -e XXX'.
Of course you can get into trouble if the old packges is broken. If you explain your actual problem we might come up with another solution than calling rpm -e.
