A server currently has httpd-2.0.63-2.el4s1.centos.2 installed (from the centosplus repo) but that version is missing some security updates. Where as httpd-2.0.52-49.ent.centos4 is a lower version, but it does have recent security updates. So I need to downgrade.

It looks like the only way would be to remove it and then install 2.0.52. Would this mess up any configurations? Should I backup all the conf files first?
