What does the process of "data migration" entail?

The process of "data migration" primarily involves moving digital content from one location or system to another while ensuring that the content remains accessible to users. This means that the data must not only be transferred but also formatted and organized in a way that users can still access and utilize it effectively. This might involve discussions around maintaining metadata, ensuring compatibility with new systems, and minimizing downtime during the transfer process.

While changing access protocols, transferring data to a different service provider, or upgrading data security measures can be part of an overall data management strategy, they do not capture the essence of what data migration explicitly involves. Data migration focuses on the movement of data and the assurance of its continued accessibility post-migration, which is why the answer highlighting accessibility during the transfer process is the most accurate representation of what data migration entails.
