Freeradius mysql acct copy

Hi. I need to copy acct packets to my billing server and save acct in standart freeradius radacct table in mysql. I'm saving acct in radacct table now, but can't duplicate them to other (billing) radius server. I've tried to use copy-acct-to-home-server but no success. As I understand, virtual server from copy-acct-to-home-server use a detail files to read acct information from default server. Is the way to don't use detail file and use mysql? Regards, Alexander.
