Data migration is the process of moving data from one location to another, one format and structure to another, or one application to another. Generally, this is the result of introducing a new system or location for the data. The business driver is usually an application migration or consolidation in which legacy systems are replaced or augmented by new applications that will share the same datasets.
Contemporary data migrations are often started as firms move from on-premises infrastructure and applications to cloud-based storage and applications to optimise or transform their company.
