``kolla-mergepwd --old OLD_PASSWORDS --new NEW_PASSWORDS --final FINAL_PASSWORDS``
is used to merge passwords from old installation with newly generated passwords
during upgrade of Kolla release. The workflow is:
- save old passwords from ``/etc/kolla/passwords.yml`` into ``passwords.yml.old``
- generate new passwords via ``kolla-genpwd`` as ``passwords.yml.new``
- merge ``passwords.yml.old`` and ``passwords.yml.new`` into ``/etc/kolla/passwords.yml``
For example::
mv /etc/kolla/passwords.yml passwords.yml.old
cp kolla-ansible/etc/kolla/passwords.yml passwords.yml.new
kolla-genpwd -p passwords.yml.new
kolla-mergepwd --old passwords.yml.old --new passwords.yml.new --final /etc/kolla/passwords.yml
