Abstract
Format migration is recognized as one of the most important potential strategies for ensuring the long-term usability of stored digital assets. The Harvard University Library is investigating the issues surrounding the design and implementation of an automated process for large-scale format migration, with initial emphasis placed on transforming GIF, JPEG, and TIFF images to JPEG 2000 form. This paper will review the findings of Harvard's initial exploration of automated migration as a participant in the Library of Congress's Archive Ingest and Handling Test and subsequent activities towards providing a migration capability for its Digital Repository Service. The significant issues in this investigation include: source population eligibility, resultant image profile selection, automated workflows, post-migration quality assurance testing, provenance metadata, final disposition of source images, and applicable preservation policies.
