    # A special case
    # Sidekiq can receive an interrupt signal during the processing.
    # It kills existing workers and reschedules their jobs using the same jid.
    # But it can cause a situation when the migration is only half complete (see https://gitlab.com/gitlab-org/gitlab/-/issues/429049#note_1635650597)
    #
    # Here we detect this case and release the lock.
