For moving your data try a migration software at http://www.ispirer.com/chyfo.html

It provides you the fastest, the easiest and the most powerful way to migrate your database into Oracle.
It allows you to extract any data from any database. It works in conjunction with Oracle SQL Loader.
The tool creates text files (CSV, TAB, fixed lenght), generates CREATE TABLE, CREATE INDEX scripts for Oracle and control files for SQL Loader.
Moving of LOBs are fully supported.
The utility has a lot of other features.
