Break free from vendor lock-in!
Contrary to popular belief, migrating from Oracle to PostgreSQL is only about as expensive as upgrading from one Oracle major version to the next. Both databases are ANSI compliant so lots of stuff just works on either database. For the remainder that doesn’t, we’ve got time-tested solutions which means reduced migration costs.

Why Migrate to PostgreSQL?
Are you sick of footing unbelievably large bills for Oracle licensing and looking for viable alternatives? PostgreSQL is an effective and open source database alternative to Oracle.
Vendor lock-in is undesirable for any organization, and if it pertains to a critical infrastructure component like your database, it can induce a huge financial drain on your business.
PostgreSQL is free forever, with unlimited usage. It is a globally trusted solution that becomes more powerful with every release through community development.

What will it take to Migrate?
Mitigate risk by evaluating before you migrate. A Migration Assessment is an evaluation of your database prior to initiation of a migration to have an upfront and accurate idea of what will be required. This will ensure a smooth switch without loss of data, unplanned downtime, or unexpected expenses. Learn more

Tools for Migrating from Oracle to PostgreSQL
We employ automated migration tools that have been developed in-house to speed up the migration efforts considerably. This ensures an error-free migration of your database to open source PostgreSQL with zero downtime.
PL/Translate – Translate PL/SQL to PL/pgSQL
PL/Translate is an advanced code translator for Oracle PL/SQL to Postgres PL/pgSQL (think ‘Google Translate’ for databases!), which is the missing part of the puzzle for quickly and cheaply migrating from Oracle to PostgreSQL. We believe in ‘code translation’ not ‘code emulation’.
ORQ – Replication from Oracle to PostgreSQL
ORQ implements powerful replication from Oracle to PostgreSQL. Whether you want to set up PostgreSQL as your standby server, or you want to use it as your Analytics database, ORQ implements efficient replication keeping your PostgreSQL instance in sync with your Oracle instance.
Fastloader – COPY from Oracle to PostgreSQL
A PostgreSQL extension containing some Oracle connection functions. It includes an SQL function that allows you to specify all the same options as a COPY statement, as well as connection details to Oracle. Data is streamed back to PostgreSQL using OCI connection, at speeds of up to 2x the speed of the COPY command.

Migration Process
The following steps are part of a typical PostgreSQL database migration checklist.
1. Initial Analysis
Before starting, it is critical to analyze the schema, data, and SQL code of the existing database to get an estimate of necessary effort.
2. Migration
Implementation of the tasks determined during analysis, including (but not limited to) schema migration, data migration, SQL migration, Oracle equivalent functions, and application code changes.
3. Testing
All workflows must be thoroughly tested against the newly migrated database. This includes workflows in the application layer as well as within the database. Any issues or bugs can be addressed in testing.
4. Performance Tuning
The new PostgreSQL database(s) need to be tuned to the client environment and usage patterns.
