We have a migration project from one salesforce org to a new salesforce org. We have migrated all the configuration and data. Now the client wants to know whether the history data (accountHistory, CaseHistory, contactHistory etc) can be migrated. I tried the dataloader and was able to export the history data, as shown in figure 1, but when I tried the import (Insert) all the history related objects disappeared. Any solution to that? and if not, any particular reason why the history cant be moved?
