extending mysql accounting for IPv6

We are deploying IPv6 capable CPE devices on a Cisco ASR9k BRAS. The ASR provides the following attributes in its accounting packets: Framed-IPv6-Address and Delegated-IPv6-Prefix. These are present in the freeradius dictionary, however, the current MySQL schema has no way to store these. I'd like to extend the existing schema to handle these additional attributes. Is it as simple as modifying the existing accounting table and accounting mysql queries? Any guidance or advice would be appreciated (freeradius-2.2.6-6.el6_7.x86_64). Thanks, --Blake
