What is Data Integration?
Data integration is the process of combining data from multiple sources into a single, unified repository. This can be useful for many purposes, such as analyzing data, creating reports, or making data-driven decisions. Data integration typically involves extracting data from various sources, transforming the data to fit a common format, and then loading the data into a target system or database. This can be done manually or with the help of specialized software tools.
By combining data from different sources, organizations can get a more complete and accurate picture of their operations, customers, and market trends, which can help them make better-informed decisions and improve their performance. There are many different approaches to data integration, including batch processing, real-time integration, and hybrid approaches. The specific approach that is used will depend on the organization’s needs and the project’s requirements.
Businesses today can eliminate data silos and maximize their use of data by integrating data in batch and real-time and employing automation to deal with problems.
Data integration can be a complex and time-consuming process, especially when dealing with large amounts of data or data from multiple sources with different formats and structures. It is essential to carefully plan and manage the data integration process to ensure that the resulting data is accurate, consistent, and valuable.
Suppose a company’s product is a mobile application. It uses a variety of tools for getting data. These tools include:
- Google Ads and Facebook Ads to acquire users through paid marketing campaigns.
- Google Analytics to track the engagement and events in its mobile application.
- PostgreSQL database to store product and user transactional data with the mobile application.
- HubSpot to track and nurture their leads.
- Marketo to send customized emails to prospects.
- Freshdesk to perform customer support.
- Netsuite for financial and account tracking.
Each of these tools has siloed information about different operations of the company. If you want to move all the data into a centralized repository, i.e., a data warehouse, then the process involved is known as data integration.
Here are some of the advantages of data integration:
- Improved decision-making
- Increased efficiency
- Enhanced customer experiences
- Greater insights
- Better data governance
- Improved interoperability

What is Data Migration?
Data migration is the process of moving data from one system or database to another. It can involve transferring data from an old system to a new one, moving data from on-premises systems to the cloud, or migrating data from one database to another.
The goal of data migration is to ensure that the data is accurately transferred and remains usable and accessible after the move. It is typically used to improve data management and access by moving data to a more modern or better-suited system. It can help organizations take advantage of newer technologies and features, enhance data security, and improve data governance and compliance.
Data migration often involves the use of specialized tools and techniques, such as data migration software, data migration APIs, and data migration scripts. These tools and techniques can help organizations efficiently and accurately transfer data from one system to another while minimizing downtime and disruptions to business operations.
So, in simple terms, data migration is about re-platforming data. For example, when a merchant is re-platforming their eCommerce store from Magento to Shopify Plus. This is a data migration process. This process involves transferring data such as product information, customer data, order history, and other relevant data from the Magento database to the Shopify Plus database.
Data migration can be a complex and time-consuming process, particularly when large amounts of data are involved or when the source and destination systems have significant differences in structure or format. It’s important to carefully plan and execute the data migration process to ensure a smooth and successful transition.
Here are some of the advantages of data migration:
- Improved performance
- Enhanced security
- Improved scalability
- Enhanced data integration
- Increased efficiency
- Enhanced disaster recovery

How do Data Integration and Data Migration Work Together?
Irrespective of major differences between data integration vs data migration, both are related yet vital concepts that are often used in the context of managing and manipulating data within an organization. They both involve the transfer of data but are used for different purposes.
Data migration is often used as the foundation for successful data integration initiatives, as it helps to define and execute a data quality strategy and ensure that the data being integrated is accurate and consistent. In some cases, data migration and data integration may be used together in contexts such as cloud data migration, where the correct integration tools can assist with the migration process and provide greater visibility and organization when it comes to the data being migrated.
For example, in a small-sized business, previously, all the data was stored in MS Excel. As the business grew, different SaaS tools were added to its deck, and Google BigQuery was onboarded as its cloud data warehouse. So, there was a shift involved in moving data from MS Excel and all other SaaS tools to BigQuery. This describes the process of cloud data migration.
Combining data integration and migration can have many benefits, such as the ability to convert business information into actionable insights, optimize business processes through increased information exchange between systems, and increase productivity across an organization by making all data resources more readily available and improving the flow of information between systems.
Explicitly, data integration and data migration can work together in several ways. For example:
- Data integration can be used to prepare data for migration: Data integration tools can be used to extract data from multiple sources, clean and transform it to make it consistent and usable, and then load it into a central repository or data warehouse. This process can help to prepare the data for migration by ensuring that it is in a usable and consistent format.
- Data migration can be used to support data integration: Data migration can be used to move data from multiple systems into a single, centralized repository, which can then be used as the basis for data integration. This can help to streamline data integration efforts by providing a single, consistent source of data that can be easily accessed and analyzed.
- Enhancing data quality: Data migration can be used to cleanse, transform, and standardize data as it is moved to a new system, and data integration can be used to enrich the data with additional information from other sources. This can improve the quality and value of the data for various business purposes.
- Enabling data-driven processes: Data integration can be used to enable data-driven processes, such as automating sales forecasting or predicting equipment failures, and data migration is often used to move data into the systems that support these processes. For example, an organization might use data migration to move data from a legacy system into a modern data platform and then use data integration to bring together data from multiple sources and systems to support real-time decision-making or predictive analytics.
- Creating a single source of truth: Data integration can be used to create a single source of truth for reporting and analysis purposes, and data migration is often used to move data from multiple systems into a central location for consolidation. For example, an organization might use data migration to move data from multiple departments or business units into a central data warehouse and then use data integration to combine the data from these different sources into a single, consistent view for reporting and analysis purposes.
In practice, data integration and data migration often go hand in hand. For example, when an organization is migrating data to a new system, it may also need to integrate data from multiple sources in order to create a coherent view of the data. Similarly, data integration projects may involve migrating data from multiple sources into a central repository and then transforming and standardizing the data to make it more useful.
Overall, data integration and data migration can be powerful processes that work together to support the data management and analysis needs of an organization. By carefully planning and executing both processes, organizations can improve their data management capabilities and derive greater value from their data.
In conclusion, data integration, and data migration are two related but distinct processes that are often used together in various contexts to manage and prepare data. So, data integration is about combing data from numerous sources into a centralized repository, whereas data migration involves transferring data from one system to another.
So, the choice between data integration vs data migration will be based on your business’s specific needs and requirements and the data management project. You need to carefully evaluate these requirements before deciding which approach best suits your needs.
