Data Migration From Oracle To Postgres Doesn't Have To Be A High Priced Nightmare

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. Because proprietary database management comes with such stringent restrictions, it is often quite a task when a company decides that it wants to perform a data migration to an open source database manager; many businesses fear this transition because of the potential for a slow-down in business as well as the risk of expensive difficulties in the process.

Fortunately, the transition from Oracle to Postgres, although daunting, can be accomplished with ease through the outsourcing of the entire project to a qualified IT firm. Whether your company is small and family owned, or a multi-million dollar corporation, the needs are the same; data migration in a quick and thorough manner from Oracle to Postgres with little interruption to the normal flow of 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 rather than moving data.

Because of the proprietary nature of Oracle, it is often necessary to look at each data migration as a unique and individual process. Often, the extraction of data necessitates large amounts of time and expertise to simply 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 overwhelmed and out of time.

Even once the format translating and data cleansing is completed, the actual task of loading the old information in the new, open source database can be time consuming and tricky. For the tech savvy business owners who have made it this far without calling in outside help, this final step of data migration often proves to be the biggest stumbling block.

Because the sheer amount of information being uploaded is so high in volume when making a migration from Oracle to Postgres, an analysis of hardware capabilities should always be performed to make sure that the upload can go forward without damaging the system. Remember that the most important part of any data migration is the ability to keep business running as usual even as the entire database is transferred. If your business is making the complicated transition from Oracle to Postgres, without the aid of outside help, the results can prove disastrous for your data and clients and heavily disrupt your ability to keep things running smoothly and effectively.
