Question 1 of 30
Consider a national heritage institution tasked with migrating a vast, multi-format digital archive, comprising decades of research data, audiovisual materials, and textual documents, from a legacy on-premises storage system to a cloud-based repository. The archive\'s metadata is inconsistently applied, and several proprietary file formats used in earlier decades are now unsupported by current software. Which strategic approach, aligned with the principles of ISO 20614:2017, would best ensure the interoperability and long-term preservation of this digital collection?
Conduct a comprehensive pre-migration audit to identify all data formats, assess their obsolescence risk, map existing metadata to a standardized schema, develop a phased migration plan with format normalization and validation checkpoints, and implement a continuous monitoring strategy for the new repository.
Prioritize the migration of the most frequently accessed data first, performing a direct file transfer to the cloud and relying on the cloud provider's built-in data integrity checks, with a plan to address format issues only if user access is subsequently reported as problematic.
Focus solely on converting all data to a single, widely adopted open-source format, assuming this will inherently guarantee long-term interoperability and preservation, and deferring detailed metadata reconciliation until after the primary data transfer is complete.
Engage a third-party vendor to perform a bulk data migration using proprietary tools that promise rapid transfer speeds, with the understanding that the vendor will handle any necessary format conversions, and then conduct a superficial review of the migrated data for general accessibility.
