dumping radius queryies

Hi all, I am on the way to migrate a freeRadius V1 to a V2. I would like to log the queries submitted to the running V1, so thaht I could test them via 'radclient' to the V2, before switching to production stage. So, on a V1.4, what kind of loggin should I enable in order to have a dump of all the queries?
