Re: Upgrading from FR 2.1.10 to 2.2.x

First, check that centos doesn't have the security issue backported For upgrade, backup your current configuration directory eg cp -R /etc/raddb /etc/raddb.backup Then install the new version 2.1.10 and 2.2.0 are config compatible apart from one single option which isn't set by default (check the release notes). Freeradius install will not touch files that already exist...so you won't get any new options/comments in your config files so may lose visibility of any new features in that regard...but new config files and modules and virtual servers will appear in your config. So, radiusd -X of your current server , capture the startup output, then do the same again after the upgrade and compare the difference. alan
