Data migration
Data migration is the process of selecting, preparing, extracting, and transforming data and permanently transferring it from one computer storage system to another. Additionally, the validation of migrated data for completeness and the decommissioning of legacy data storage are considered part of the entire data migration process. Data migration is a key consideration for any system implementation, upgrade, or consolidation, and it is typically performed in such a way as to be as automated as possible, freeing up human resources from tedious tasks. Data migration occurs for a variety of reasons, including server or storage equipment replacements, maintenance or upgrades, application migration, website consolidation, disaster recovery, and data center relocation.
Child migration
Child migration or "children in migration or mobility" (sometimes more generally "children on the move") is the movement of people ages 3–18 within or across political borders, with or without their parents or a legal guardian, to another country or region. They may travel with or without legal travel documents. They may arrive to the destination country as refugees, asylum seekers, or economic migrants.
