Hi,
We recently done the similar migration for one of our customer. We used all
opensource tools to achieve this migration process.
We used Pentaho Data Integration tool for doing Online DB migration, which
took minimal downtime with CDC{Change Data Capture} approach. Also, we used
Ora2Pg tool to migrate the DB objects with some manual syntax modifications.
Regards,
Dinesh
