Upgrading 1.0.5 to 1.1.4

Hi everyone. I'm currently running FreeRadius verison 1.0.5 on a Linux Redhat 9 server. I need to upgrade my FreeRadius to the latest, greatest version 1.1.4. Awhile back i upgraded from 0.9.3 to 1.0.5, but for the life of me i can't remember how to do the upgrade without completely messing up my current configuration. Can anyone provide exact instructions on how to go from 1.0.5 to 1.1.4 without changing the config files? Thanks.
