It Is Possible: Data Migration From Oracle To Postgres Without Overextending The Budget Or Losing Your Mind

By Miker C. Rax


A company in the process of a data migration from Oracle to Postgres is usually at the beginning of a long and sometimes treacherous road. Since the use of proprietary database management often brings with it nightmarish scenarios when attempting to make the transition to open source database management, many business owners fear their clients will suffer and their costs will soar as they make the necessary changes to their method of storing vital information.

Thankfully, the switch from Oracle to Postgres can be painlessly handed off to an outside IT firm. Every company, from the largest corporation to the smallest family owned business wants to see the same result; a seamless and painless transition to an open source database manager without any disruption to everyday business. The benefit of outsourcing the tedious and complicated tasks of analysis and planning for a smooth and successful data migration is that you will be able to focus on your everyday business operations and clients' needs instead of moving data.

The fact that Oracle is proprietary in nature makes it all the more difficult to plan the unique path required to safely migrate a specific company's data. Sometimes, the extraction of data necessitates large amounts of time and expertise just to translate format so that the migration is even possible. Even this simple process can often leave those who attempt to complete a data migration themselves discouraged and out of time.

After the data is all safely formatted and cleaned for transfer, the task of loading it into the new open source database can be extremely time consuming and difficult. Many tech savvy business owners make it as far as this, and then are forced to call in for help anyway because the final step proves too big a task to complete without help.

When dealing with the sheer amount of volume present in a migration from Oracle to Postgres, it is important that a thorough evaluation of your business's hardware take place before the upload can be completed or you will risk a massive slowdown or even crash of your system. Bear in mind that the goal of any data migration is to make it as seamless and undisruptive as possible to your daily business needs. If you are thinking of a move from Oracle to Postgres without the assistance of an outside IT firm, you are doing so at great personal and professional risk to your business and your clients.
