How is possible to not check area or iteration history ?

during sycnhronization, i would like to be able to move some iterations without to remove the revisions sync setting.

When a iteration is deleted, every Work items that reference the iteration in their revisions can not be synchronized !

You would need to run two migrations. One with a query scoped for the work items that you do want to migrate history with ReplayRevisions set to true, and another scoped for the rest with ReplayRevisions set to false.

Correct, if the iteration for the migration does not exist then the work item cant be migrated. You would need to add a mapping in the Field Map for that Iteration. This would affect ALL work items in scope for that migration under that Iteration.
