 When we are working on the Sitecore migration project. if the client wants to see the item history of the items it will be blank as shown below. As part of the migration, we need to migrate the item history data as well. to do so go to the existing sitecore_master database.                                           Please consider restoring the workflow history simply by copying the entries from old WorkflowHistory table to your new database.
