The Content Platform Migrations Working Group was formed to address the increasing number of platform migrations in the publishing and library communities. With publishers migrating every 5-10 years, content platform vendors migrating 5-10 times per year, and librarians experiencing over 10 migrations per year, there is a lack of coordination and communication between stakeholders. The working group aims to develop recommended practices to standardize migration processes and improve communications before, during, and after migrations through stakeholder interviews, guidelines, checklists, and a communications plan to minimize disruptions to users.
