Quick Launch

Once you stored conversion settings into profile you can run the program in Quick Launch mode. Just launch Windows Explorer and double-click on the profile description (.o2p) file with left mouse button. This will cause Oracle-to-PostgreSQL wizard to launch conversion loading the necessary settings from the specified profile. Then you will be taken right to the screen with progress of conversion without entering all conversion settings.


Oracle-to-PostgreSQL implements synchronization as combination of insert Oracle records that are missing in PostgreSQL table and update existing PostgreSQL records with Oracle data. For synchronization purpose source and destination tables must have identical structures and have primary key or unique index defined.

If you need more options to configure the synchronization or want to reduce duration of the process via "incremental" technique, take a look at Oracle-PostgreSQL Sync, special product to synchronize Oracle and PostgreSQL databases.


Oracle-to-PostgreSQL converts about 90% of syntax constructions involved into Oracle "CREATE VIEW" statements. Some of the conversion rules are described into this whitepaper.

PostgreSQL script file

Oracle to PostgreSQL converter allows users to migrate Oracle database into PostgreSQL format even when there is no direct connection to the destination server. Following this approach, the program exports Oracle data into a local PostgreSQL script file instead of transferring it to database server directly. The output file contains SQL statements defining all tables and inserting the data. This article explains how to import script files into PostgreSQL database.

Try before you buy

Still not sure the program fits your needs? Try free demo version with limited features. It will allow you to convert only 50 records for each database table, it does NOT convert queries/views and foreign keys. Test the quality of the demo and come back to place an order if satisfied with the results.
