Many items were migrated to Alma that had an Item Process Status in Aleph. These items were given a Process Type of "Technical - Migration" in Alma and the Item Process Status was added to the item's "Internal Note 3" field. In general, all items with a Process Type of "Technical - Migration" are suppressed from view in Primo. Please see the following Libguide page for directions on how to find these items and remove the "Technical - Migration" Process Type.
