All main Oracle data types (including XML, CLOB and BLOB) are supported for data migration to MongoDB and back. You are able also to view and manage MongoDB collections data and export it to a readable JSON file format. The data migration process can be parallelized up to 20 degrees providing a very high migration performance of big amounts of data.
