Moving from Trixbox Pro to FreePBX

I am looking at implementing a FreePBX appliance system to move from Trixbox Pro and combine the analog devices and sip-dect devices I had been supporting on a separate Trixbox CE server onto the single device (Fonality does not support multiple phones at the same IP, so only my direct IP deskphones are on the Pro server.
Is there a collection of files or dabases I can mine on the Trixbox PRO system to capture my existing extensions and config to import to the FreePBX system to make the transition essentially a swap-out for the TrixBox users?
