freeradius upgrade

Hello all, I'm new here and freeradius newbye. I have to upgrade from freeradius 1.0.1 to 1.1.1 on red hat linux. Do you have any advice or help ? The default 1.0.1 installation is the same as the new one 1.1.1? I mean does it install file in /usr/local/etc for configuration file, /usr/local/var/log for log files and /usr/local/lib for libraries ? .. then configuration file I suppose won't be changed, right? .. then the procedure is the same as intsllation procedure? thanks Giuseppe
