rpm -Uvh - How to replace modified config file

The question is a duplicate from Stackoverflow site

I upgrade rpm package with rpm -Uvh command.

Original and new configuration file is the same, but current file on disk has been changed.

This situation described in Original file = X, Current file = Y, New file = X

Due to delivered fixes in a new rpm file I want to overwrite this configuration file anyway. Is there way to do it ?

The configuration file appear in %config section of rpm spec.

--replacefiles, --replacepkgs options don't help here.

Thanks
