When a question is migrated, all its answers get migrated with it (presumably). One thing I just noticed is the option to `undelete` my answer on the `?noredirect=1` landing page for the question (i.e. as it was before migration).

Why does it say that my answer is deleted as opposed to migrated? What happens if I undelete it? The [FAQ][1] does not explain answers being deleted due to migration.
