Types of Data Migration

Types of Data Migration


Data migration is the process of transferring data from one system to another. While this might seem easy and straightforward, it has to go through a series of preparation to achieve.


Companies undertake data migration of different reasons.. It can be a server or storage equipment replacement, maintenance or upgrade, application migration, website consolidation, disaster recovery, and data center relocation. Many of these are positive reasons as the company is upgrading from an outdated medium into a higher performance system that allow data to be stored more efficiently and securely.


Data migration can be broadly categorised into 4 different types.


Storage migration

Company may choose to rationalise the physical media to technologies that offer more efficient storage options. This will enhance the performance of storage.


Database migration

This type of migration involves moving data between two database engines.

Also known as Schema migration, this method involves database change and is performed programmatically by using a schema migration tool.


Application migration

This type of migration occurs when an organization switches from one application to another that has a different data model. That being said, the operating system, configurations and data language can all be unique. These factors make migration even more tedious.

Business process migration

Business processes operate through a combination of human and application systems actions, often orchestrated by business process management tools. When these change they can require the movement of data from one store, database or application to another to reflect the changes to the organization and information about customers, products and operations. Examples of such migration drivers are mergers and acquisitions, business optimization, and reorganization to attack new markets or respond to competitive threat.



While data migration often for a good reason, it may impact the business operation negatively when it creates extended downtime, compatibility and performance issue. Organisations may adopt various strategies such as technologies to help them minimise these impacts.
