I am trying to do so and I am getting the following error: Invalid status code: 400, response body: [{"errorCode":"INVALIDJOB","message":"InvalidJob : No create/update access for object:CaseHistory"}]
Is it somehow possible to upsert since I have read that this is a read only object. I am trying to migrate the records from one org to another
The audit logs are immutable by design. That is to say, they are designed to be compliant with certain legal processes, like financial audits, security compliance, and even as a level of standard for evidence in a court of law. While it would be helpful to be able to migrate between orgs, that's just not possible. It took salesforce.com a very long time to implement the "Set Audit Fields upon Record Creation", as they were reluctant to break useful audit feature. But they did make it opt-in, so technically it is the subscriber's choice to make those fields less useful.
