# Copyright (C) 2012-2022 Zammad Foundation, https://zammad-foundation.org/

# This migration removes all pre-existing user sessions
# so that they can be replaced with sessions that use "secure cookies".
# It is skipped on non-HTTPS deployments
# because those are incompatible with secure cookies anyway.
