So your SaaS product is a success and the users are growing. The
growth also means heaps of big data. Even though you are satisfied with the database management right now, a more efficient and cost-effective approach will become imperative for long-term business growth.
For example, shifting the infrastructure from Windows Azure to Amazon AWS is a cost-effective move and quite effective too. However, if you are
forecasting that the database will outgrow the infrastructure in near future
and you are also using a sharded (RDS instances) multi-latency strategy, the cost can go out of control. That’s because it will demand the integration of more shards and tools like Amazon RDS for SQL Server cost more per
Now, Amazon RDS for SQL Server works fine and many users are satisfied
with it. It is widely used, comes with a plethora of helpful tools, and expert
personnel. But when it comes to cost management and specific business needs, you need a less expensive, open-source alternative that can handle big data efficiently.
So what are some of the most commonly used Database Software? Well, when considering a budget-friendly and robust database management software, MySQL and PostgreSQL are the go-to choices for many companies. PostgreSQL does a better job of managing concurrency. SQL Server, on the other hand, is not so efficient in this department and it can cause deadlocked reports in the log.

PostgreSQL seems to be a better option in handling a scenario where multiple processes are trying to access shared data instantaneously. Now, the million-dollar question; how do I import data into PostgreSQL? This blog will help you understand the procedure but before that, let’s try and understand some coding differences between SQL Server & PostgreSQL that will help you in the data migration process.
Although both follow the American National Standards Institute’s (ANSI) standards as the official language of database administrators, there are distinctions between the syntax and data types.

Now that you know how to deal with the coding aspect, it is time to move the data from SQL Server to PostgreSQL. The data transfer process may slow down or even shut down the application for a while (depending on the size of the data), so it is a good idea to inform users beforehand. Here’s what the migration process usually looks like:
Once you are live with the new database engine you must test the app and the migrated database. Make sure to check the following aspects:
If you are still in two minds about the process, it always a good idea to consult an experienced software development company.
