What does data migration refer to?

Data migration refers specifically to the transfer of data between storage types or formats. This process is essential when organizations upgrade their systems, move to a different data storage solution, or integrate new technologies. Data migration involves various tasks, including extracting data from the source, transforming it if necessary (to fit the new format or requirements), and loading it into the target system.

This is an important aspect of data management, as it ensures that data remains accessible and useful throughout changes in technology or organizational needs. The successful execution of data migration ensures the integrity and accuracy of data during the transition process, and it can facilitate the optimization of data storage and access methods.

Other options provide different definitions or concepts that do not accurately represent the process of data migration. For example, permanently deleting data, creating new data formats, or analyzing data usage are distinct processes unrelated to the act of transferring data between storage types or formats.
