Upgrading from AMP to FreePBX (copy database)

Hi,
I have [email protected] 1.1 (Asterisk 1.0.7) with AMP 1.10.008. I have built a new box with CentOS 4.4, Asterisk 1.2.12, FreePBX 2.1.2, (not [email protected]).

Is it possible to export the database from AMP and import it into FreePBX?

Is there a document that show the tables and fields used by FreePBX?

Thanks
