[openstack][kolla-ansible]about upgrading openstack

Hello.

I read this doc about upgrading openstack

https://docs.openstack.org/kolla-ansible/latest/user/operating-kolla.html

But I would like to know if

We install a new kolla-ansible(version to upgrade) on the new deployment host, apply changes with password.yml, global.yml and multinode and keep old /etc/kolla/config. Finally, we use kolla-ansible deploy instead of kolla-ansible upgrade.

Are these steps ok? Pls correct me if I am wrong.

Thank you. Regards
