> ##What causes a migration to be rejected and what happens after?
>
> A question can also be rejected by the target community after it has already been migrated if it gets closed as a reason other than duplicate, or gets deleted (usually by the owner) on the target site. When a question which was already migrated gets rejected, the entire process of the migration is reversed. All the answers are returned to the origin site and undeleted* and are subsequently deleted on the target site.
