The easiest approach may be to use SQL Anywhere's dbunload utility. This will create a reload.sql file that you can modify to match MySQL's syntax, along with csv files with the data.
ASA version 7 is over 9 years old. Have you tried one of the newer versions of SQL Anywhere? The SQL Anywhere Version 11 Free Developer edition was just posted on the Sybase website:

The Developer Edition allows free development, and demonstrates much faster performance than MySQL on many different types of applications. Perhaps it would solve your needs, without the need for migration.
