The next ten years, the business will change more than it did in the previous fifty.” -Bill Gates

So, you want to migrate from Oracle to PostgreSQL? It’s understandable. PostgreSQL has so many outstanding qualities, which could be why you’re considering making the change. However, business owners and developers always have a multitude of questions, concerns, and hesitations before taking such a big leap.

It can be stressful when migrating from one database to another. You have to create an effective “game plan” and prepare days in advance to make sure the transition runs smoothly. You need to make sure that the code is compatible so that you can efficiently migrate the data from one system to the next. You also need to make sure that there little to no disruption for your users so that your business can get back up and running quickly.

And the cost - let’s not forget to mention that. You never know for sure what problems are going to arise and how you are going to resolve them quickly. Downtime is never a good thing. Most companies hire experts to make sure that there is a seamless transition. This can be very expensive, not to mention the loss of money that is going to occur while your business is not operating.

After all of that, you’re probably ready to back out. BUT DON’T PANIC! Every business is different, and I am sure that there are more topics of concern. But trust me, you’re not the first business to go through this, nor the last. Anything that you’re going to experience, more than likely has happened before and a resolution has already been found. There are ways to simplify the migration, reduce the cost, and your business may have little to almost no downtime. Despite all of the possibilities, take a look at these reasons why other companies just like yourself are still deciding to migrate from Oracle to PostgreSQL.

1. Exceptional Reputation

PostgreSQL has been used by businesses for over 20 years and is one of the most popular open-source relational databases out there. For two years in a row this database has won the “DBMS of the Year Award,” and it doesn’t look like they are going to be giving up the title anytime soon. The design and function of this database enable developers to manage Web services and data warehousing for back-end applications effortlessly.

The best part about it all is that an organization owns it and not a corporation. They are committed to providing a free and secure database, with the backing of a large community of developers. Its performance is equal to, if not better than Oracle, Microsoft, Sybase, and other similar databases. Unlike its competitors, PostgreSQL receives new features every single year, while other contract-based systems produce new features every two to three years. This shows its strength of innovation, which is why many are flocking to use this system.

There is also reduced uncertainty with this system. If a problem should arise, businesses can quickly address it by paying for additional tech support services. This group of experts is generally able to resolve a bug in a few days or less. This only adds to the confidence that business owners have with this system.

2. Reduce Business Costs

We can all agree that Oracle is a functional database that can accommodate the needs of businesses. That’s just the truth. I mean, come on. If they weren’t, they would simply be out of business, and this wouldn’t be a topic of discussion. But are they the most cost-effective option? Let’s look at the numbers.

Oracle has multiple payment plans, from a “Pay as You Go” option to a “Monthly Flex” option. This is great because you can choose what your business needs and forget the rest. However, if you look at their licensing packages as a whole, it’s a different story. The Standard Edition license is $17,500 per unit, and the Enterprise Edition is $47,000 per unit. These numbers are certainly a great reason to start looking for alternative options.

Let’s examine PostgreSQL. It’s free. There are no hidden costs, license agreements, or those annoying demos that only take you so far, before cutting you off when you need it the most. Therefore, you’re getting one of the best databases out there, there are no financial commitments, and you have the option of getting 5-star technical support to handle any problems that should occur. Who could object to that? Your business is going to save so much money by making this change.

3. Amazon Web Services (AWS)

As a business owner, you should be able to walk into the office, run your daily sales reports, hold your staff meetings, and make corporate decisions to ensure your business becomes number one within your industry. Your staff meetings shouldn’t include reports that your customer service team was not able to fill orders because the system crashed. Thus, causing you to lose x amount of dollars during that time. Believe it or not, small businesses experience this exact scenario more often than you think.

Besides, you have to oversee an IT staff that works tirelessly to scale your network as your business grows, manage software installations, complete security patches, and additional daily tasks. To relieve some of these stressors, Amazon has carefully crafted services to cover all these business needs.

  • Amazon Relational Database Service (RDS)

Amazon RDS, also known as Relational Database Service, is a great way to remove all the extra hardware located in your server room, leaving you only responsible for optimizing your applications. No more IT staff to rack, stack, and repair the equipment. You can focus on running your business.

  • AWS Schema Conversion Tool (SCT)

SQL code combability is critical with migrating databases. Schema Conversion Tool (SCT) is designed to scan the original database and make sure that the data structure is harmonious with the new system. It only produces a schema or model and doesn’t move the data. The assessment report can then be reviewed, thus enabling you to predict any problems that may arise during the migration process so that you can plan effectively.

  • AWS Database Migration Service (DMS)

With DMS, also known as Database Migration Service, you can virtually move data from almost anywhere, to almost anywhere. You can securely replicate the data within your database and start in a matter of minutes while practically no downtime. Any alterations in the SQL code will already be known by running the Schema Conversion Tool first, which can save you valuable time during the migration.

Overall, migrating over to PostgreSQL is not as complicated as you might think. You need to ask the right questions and find the right tools to ensure that your migration runs smoothly. Fear and nervousness generally come from the unknown. Once you take the time to draw out a plan, you will have increased confidence and resounding assurance that you’re making the right decision for your business.
