Upgrading from 1.17 to 2.14 MySQL schema

Hi all, I'm in the process of migrating our RADIUS servers from 1.17 to 2.14. I've scoured all over for any information relating to the migration of the MySQL database. Am I just missing something here, or are the two versions completely non-compatible? If this is the case, I'll have to write a translator to migrate the data from the old DB into the new one. Steve
