Presented at Open Repository 2018, Bozeman, Montana The National Library of Naples is the third largest library in Italy. In 2007 a digital library system was created in order to enhance the immense cultural heritage stored in its warehouses. Today, after 10 years, the Library chose to move its Digital Library Management System to DSpace-GLAM. DSpace-GLAM is a specific DSpace-CRIS configuration for the description, management, analysis and preservation of digital cultural heritage. The choice of a solution built upon DSpace, the most used open source Digital Asset Management System in the world, supported by a large community and by the Duraspace foundation, is mainly related to sustainability issues. During the first half of 2018, digital contents will be migrated into the new system. The presentation will illustrate the migration workflow and the expected results.
