For a SAVF the answer is No, A SAVF can contain multiple objects (files, programs, complete libraries, etc).
You can copy the data from a single file to a .csv and use that for migration.
Or you can write something yourself (using PHP or some other language) to read the AS400 file and run an SQL statement to INSERT the records into a MYSQL Table,
Or you can purchase a product to do this for you . RDBConnect is one I think of.
