Data migration
Post-migration: After data migration, results are subjected to data verification to determine whether data was accurately translated, is complete, and supports processes in the new system. During verification, there may be a need for a parallel run of both systems to identify areas of disparity and forestall erroneous data loss. Additional documentation and reporting of the migration project is conducted, and once the migration is validated complete, legacy systems may also be decommissioned. Migration close-out meetings will officially end the migration process.
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.
