I use Oracle not MySQL
but I do recall seeing MySQL has an administrator kit with MIGRATION function
and then all you need is the ODBC or JDBC connector driver
to hook up to Oracle and move your schemas.
So that may solve moving data, but perhaps roles and such will need manual rebuild
and of course PL/SQL might need modification to accommodate differences in Oracle SQL/PLSQL and MySQL
you may find some Oracle functions in use not supported by MYSQL or renamed.
