Data Migration

Definition

Data migration is the process of permanently transferring data between storage types, formats, databases, or computer systems. The migration of data from one storage location to another, or from one format to another, can be a complex complicated process requiring preparation, extraction, and automation. 

Preservation principles are essential during data migration to ensure that data is not lost or damaged when it is being migrated. Data migration can happen for a variety of reasons, including changing vendors, upgrading to a new system or software version, or migrating from an obsolete software to a more modern one.

Examples

Legacy data that was collected using Microsoft Access and Excel spreadsheets is migrated to REDCap for better organizing and security of data.
