Description
When migrating an ObjectID-based relationship class with versioned data, a validation check is performed to ensure that there are no invalid ObjectIDs or GlobalIDs. An ObjectID or GlobalID is invalid if one ObjectID is mapped to more than one GlobalID, or one GlobalID is mapped to more than one ObjectID. If this validation has failed, a list of the mismatched IDs will be provided and the Migrate Relationship Class tool will abort the migration.
