The State Library of North Carolina preserves and provides access to over 162,000 digital files from its collections. It uses CONTENTdm for access and had been storing digital content on a local server. It decided to migrate this content to DuraCloud for additional preservation storage. The migration process involved exporting metadata from CONTENTdm, file lists from the local server, checking file names and checksums, and identifying any missing files. Test uploads were done to DuraCloud before running a full sync of content over multiple days. Ongoing uploads will now be done using DuraCloud's tools. Lessons learned include the need for improved metadata handling and more automated monitoring and integration with access systems.
