Indeed, I have already started to backup everything, thanks

So, now I have all my nodes running Ubuntu 16.04.

I am in a HA configuration.

I am using Openstack-Ansible an my actual openstack version is Newton 14.2.8.

The users identify through the organisation LDAP.

For now we are running :

- Keystone

- Nova (local storage)

- Cinder (NFS)

- Glance

- Neutron

- Heat

Apparently they also tried to install Ceilometer it had weird behaviors and overwhelmed the servers so it was deactivated before my arrival...

After (or is it better during?) the upgrade we would like to add:

- Ceilometer

- Gnocchi

- other tools to monitor the VMs usage and to send reminders of usage to the users (grafana...)

Thanks for the advice,

Have a great day

Cecilia

Welcome! Can you tell us a bit more about your environment? What
distribution is your cloud running on, and what deployment tools are you
using? Also, are your infra nodes an HA configuration?

No matter what, you definitely want to have really solid backups of all of your databases and of your configs. And I'd recommend devising a rollback or recovery plan before starting the upgrade.

Cheers,
Jill
