At what point is a migration complete?: What happens after you redirect that URL

When you think of a repository migration, it’s easy to think of that final step of redirecting the URL and going live on the new platform as the finish line, but in many ways that’s when the real work begins. The migration team at the UMass Amherst Libraries drafted their metadata mappings, wrote emails to collection administrators, updated the repository libguide, worked closely with the Graduate School for ETD submissions, and thought through content freeze contingency plans. And yet, all that careful and thoughtful work did not prepare them for what came next. From blocking Google requests, identifying items that shouldn’t have migrated, lifting pre-emptively placed embargoes, to cleaning up bad date formats, discovering that previously suppressed metadata had been exposed, and managing expectations of eager submitters and users, we’ll present to you some lessons learned from the migration of ScholarWorks@UMassAmherst from Digital Commons to DSpace.
