Migrate DSpace from 5x to 7x - How do we did it in our national open access service at RCAAP

The RCAAP network, crucial for promoting Open Science in Portugal, includes the Institutional Repository Hosting Service (SARI), which hosts 28 repositories. Facing the challenge of migrating from DSpace 5.x to DSpace 7.x, the process unfolded in phases. The creation of DSpace 7++, incorporating additional integrations, marked the initial step. A pilot project involving two institutions refined the migration process. With a focus on improved user interfaces, recent technologies, customization, and new integrations, DSpace 7.x was chosen. Despite compromises and acknowledged usability issues, the migration aimed to align with the community's needs. The ongoing evolution prioritizes aspects adding value to what DSpace delivers within the broader scientific ecosystem. Notably, lessons learned emphasize the significance of constant improvement and prioritization of features aligned with community needs.RCAAP网络是葡萄牙推广开放科学（Open Science）的核心支撑平台，旗下包含机构知识库托管服务（Institutional Repository Hosting Service，简称SARI），该服务目前托管28个机构知识库。该平台面临从DSpace 5.x迁移至DSpace 7.x的技术挑战，整体迁移工作分阶段推进。集成多项额外系统集成功能的DSpace 7++版本研发，成为本次迁移的首个步骤。由两家机构参与的试点项目，对迁移流程进行了优化完善。综合考量优化后的用户界面、新兴技术、定制化需求及新增系统集成功能等因素，最终选定DSpace 7.x作为迁移目标版本。尽管迁移过程中存在一定妥协，且存在公认的可用性缺陷，但本次迁移始终以贴合社区需求为核心目标。当前仍在推进的迭代优化工作，优先聚焦于能够为DSpace在更广泛的科学生态系统中所提供的服务创造附加价值的方向。尤为值得关注的是，本次迁移过程中总结的经验教训，凸显了持续优化以及优先开发贴合社区需求的功能的重要意义。
