Hi Winicius,

Thanks for raising this. You're right, we should re-order those instructions to generate configuration first. I've raised a patch for this: https://review.opendev.org/c/openstack/kolla-ansible/+/948428

The procedure isn't strictly mandatory for A->C, but if you don't want them you'll need to disable quorum queues in Caracal by setting om_enable_rabbitmq_quorum_queues: false. However, I'd strongly recommend against this as quorum queues make using RabbitMQ much more robust.

Cheers,

Matt

Hi community o/

I've got a little confused about the procedure[1] to change the type of queues to quorum queues. The documentation says that it is needed to stop the services that use Rabbit, but in some tasks in `genconfig` step, some APIs must be up, for example, in[2]. I think the documentation is not too clear, or I just missed something.

So, I need to stop services and turn on the APIs? Will it affect the procedure of changing the queue type from classic to quorum?

Another question is: when upgrading from Antelope to Caracal, is this procedure mandatory?
