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.
UVC-based preservation
Preservation of digital resources is of a paramount importance for deposit libraries, research libraries, archives, government agencies, and actually most organizations. The dominant approach to digital preservation is migration. Migration entails making periodic transformations of archived information into new logical formats as their native formats, or the software or hardware on which they depend becomes obsolete. The notable danger of migration is data loss, and possible loss of original functionality or the ‘look and feel’ of the original format. Furthermore, digital migrations are time consuming and costly as the process requires converting the format of every document, in addition to copying converted bit streams to new media as necessary.
