Companies that utilize legacy data storage have a hard time keeping up with competitors and delivering services that clients expect to be perfectly suitable for their needs. As your organization grows and evolves, you can find yourself in need of novel tools for data processing and migration. Data migration is relocating data between systems. It is a complex process that needs careful planning to avoid durable downtimes and ensure successful results.

However, some tools can assist businesses in this process and make it less painful. In this article, we’ll make a comprehensive overview of the best tools for data migration and discuss their pros and cons to help you make an informed decision.

Introduction to Data Migration Tools

Data migration software is designed to help move data (or entire business environments) from one platform to another. These tools come in handy when a company decides to update its systems and data storage or when a merger takes place — both are time-consuming and labor-intensive tasks. These tools are practically indispensable for large enterprises that handle vast volumes of data and have complex databases.

There are other reasons to refer to data migration tools.

  1. They take care of the data transfer process, ensuring its accuracy and efficiency: automation helps avoid data loss, corruption, and human error that may emerge with manual data migration.
  2. They help streamline business processes: a business’s ability to adapt to innovation defines its competitiveness. With proper migration tools, companies can move critical data between systems and apps without disrupting core operations.
  3. They reduce costs and save time: manual processes necessary to transfer data always take more time and money than automated ones (for large organizations in particular). Instead, with the right migration tools, companies focus on their growth.

Top Data Migration Tools

Let’s take a look at the most popular data migration tools, their features, pros, and cons.

AWS Database Migration Service

A cloud-based service by Amazon Web Services (AWS) is designed to facilitate data migration from a variety of sources: on-premise databases, data warehouses, and other cloud environments to a wide range of target destinations (including AWS databases and data warehouses). AWS DMS also offers one-time and continuous data replication for various systems, like MySQL, MariaDB, PostgreSQL SQL, and NoSQL databases. Their replication engine moves data with minimal downtimes. The process looks like this:

Using Data Migration Tools: Best Practices

We’ve created a list of tips to help you ensure a smooth transition of data from one system to another:

  • Comprehensive plan. Before actually migrating the data, plan out the entire process from start to finish: pre-define timelines, roles and responsibilities, and contingency plans in case any issues or delays arise.
  • Data mapping. This entails identifying and defining the relationships between the data in your current source and target destination systems. Businesses should pay special attention to this process if they want their databases to be transferred accurately.
  • Data cleansing. Before you begin the migration process, identify and fix any errors or inconsistencies in the data. Duplications, naming inconsistencies, and data format errors are just some of the problems that often remain hidden. So, make sure the data is accurate before migration to avoid issues down the line.
  • Testing. This is another vital step in the migration process. Conducting test migrations to the target destination will help ensure that all matters are taken care of and that the data can be moved. Companies often test not only individual data sets but also overall system functionality.
  • Validation. The final step is verifying that the migrated data is valid and meets the end user’s expectations. This involves post-migration checks, which aim to ensure that the data is usable in the new system.

Case Studies

Let’s take a look at real-world cases of successful data migration.

Wayfair, the top eCommerce company in the US, migrated its on-premise MySQL database to Amazon Aurora using Amazon DMS. This migration took only six months and involved nearly 200TB of data. What’s the end result? Significant reduction in database-related costs.
