Although D365 has an out of the box entity for migrating cases (Case Detail), no entitiy is available to also migrate the related logs linked to the case. As a result, an essential part of the case's history can 't be migrated and is lost. Therefor, a new entity (caseLogEntity) should be created to preserve this data. In relation to the entity 'Case Detail', there's another suggestion. The validateStatus() method for the caseDetailBase table does not allow us to insert a record with status 'Closed' or 'Canceled'. As we see it, this should be possible when migrating cases.
