.. note::
With upgrade to 2024.1 (Caracal) release usage of RabbitMQ Quorum Queues
is enabled by default. Migration to usage of Quorum Queues results
in prolonged downtime for services during upgrade.
To reduce downtime you might want to set
``oslomsg_rabbit_quorum_queues: false`` at this point and migrate to
Quorum Queues usage after OpenStack upgrade is done.
With upgrade to 2024.2 (Dalmation) release and beyond, usage of RabbitMQ
Quorum Queues is mandatory to ensure high availability of queues. If you
had previously set ``oslomsg_rabbit_quorum_queues: false``, please
consider migrating before continuing with this upgrade which uses RabbitMQ
4.x.
Please, check `RabbitMQ maintenance <https://docs.openstack.org/openstack-ansible/latest/admin/maintenance-tasks.html#migrate-between-ha-and-quorum-queues>`_
for more information about switching between Quourum and HA Queues.
