Database migration software from DBConvert helps you convert and sync data
from Oracle to PostgreSQL, Amazon RDS PostgreSQL, CockroachDB, or Heroku Postgres servers.
Why migrate from Oracle to PostgreSQL?
There are many reasons why you might choose to migrate from Oracle to
PostgreSQL. Here are just a few of the benefits:
In addition to the cost of Oracle licenses, using Oracle databases
introduces additional fees for features such as partitioning and high
availability, and expenses can rise rapidly. PostgreSQL is open source and
free to install and use.
PostgreSQL is an open-source database and readily available from public
cloud providers, including AWS. With PostgreSQL, you don't run the risk of
being tied to a vendor.
Because PostgreSQL is open source, countless extensions and add-ons can
dramatically improve database performance, and many of them are free to
use. In Oracle, the cost of similar features is increasing rapidly.
Switching from Oracle to PostgreSQL is a costly and time-consuming task. For
heterogeneous migrations such as Oracle to PostgreSQL, you must ensure that
the schemas/ data types of the source Oracle database are compatible with the
target PostgreSQL database.
How to convert Oracle to Postgres?
Let's compare the well-known open-source tool,Ora2pg , with the DBConvert /
DBSync DB migration tools.
Ora2pg is a free and open-source Perl-based tool used to
migrate an Oracle database to a PostgreSQL database. It connects your Oracle
database, automatically scans and retrieves its structure or data. Then ora2pg
generates SQL scripts for loading data to your PostgreSQL database.
Ora2pg is cross-platform software supporting Windows and Linux operating
- Ora2pg is free and open-source.
The installation procedure for Ora2pg, including Perl modules, Oracle, and
Postgres clients, can be complex depending on the OS version and even more
complicated if you do the same on Windows. There are even many guides on
setting up ora2pg that are still a little tricky.
Ora2pg is a command-line tool and thus doesn't have a visual interface.
Ora2pg serves data migration tasks from Oracle or MySQL to PostgreSQL. In
other words, it transfers databases in ONE direction only.
DBConvert and DBSync are proven database migration tools for
converting and synchronizing data from Oracle to PostgreSQL.
DBConvert software is highly customizable and allows you to quickly and easily
export data from Oracle to Postgres using a
comprehensive graphical interface.
In DBConvert products, the target database is presented in the form of a tree,
which dramatically simplifies the setting of parameters. The proven advantage
of DBConvert software is that
non-professional users can effectively use it.
Select the database objects to migrate.
By default, before migration, all database objects, including database schema
(tables, views, indexes) with unique, primary, foreign keys, are selected.
You probably don't need to migrate everything from Oracle to PostgreSQL
database. Often, you shouldn't waste time migrating legacy objects that you no
longer need, such as backup data and temporary tables from previous
Just select only the objects you need before converting.
Database migration directions.
In any combination, using our Oracle to PostgreSQL
converters, data conversions between the following databases are possible:
keeps your databases in Sync
with Update, Insert, and Drop synchronization features.
helps to update data in both source and destination databases simultaneously.
Change Data Capture (CDC)
has become the ideal solution for low-latency, reliable, and scalable data
replication between Oracle and PostgreSQL in high-velocity heterogeneous data
Trigger-based CDC Synchronization
algorithm is designed to accurately analyze the destination database data and
instantly track changes in both databases.The trigger-based sync method
increases recurrent synchronization speed in times.
For recurring synchronization and conversion tasks, use theBuilt-in Scheduler.
DBConvert Wizard interface guides you through several easy steps to perform
fast and robust data migration and sync from Oracle to PostgreSQL databases.
