Trixbox upgrade to the new BETA?

Running Trixbox and would love to migrate to the latest FreePBX beta for testing. I understand I can force for the trunk with a tarball, but would rather have the Centos 6.3 final OS too.

I loaded the latest 32 bit 11 FreePBX ISO on a second computer… so I do have both up at the same time if that helps migrating.

Any suggestions?
