Upgrade: Ussuri to Victoria

This page contains notes specific to the Ussuri to Victoria upgrade path. See the main OpenStack upgrade page for full coverage.

FWaaS project retired

The Firewall-as-a-Service (FWaaS v2) OpenStack project is retired starting with OpenStack Victoria. Consequently, the neutron-api charm will no longer make this service available starting with that OpenStack release. See the 21.10 Release notes on this topic.

Prior to upgrading to Victoria users of FWaaS should remove any existing firewall groups to avoid the possibility of orphaning active firewalls (see the FWaaS v2 CLI documentation).

OVN data plane downtime

OVN versions less than 22.03 will lead to downtime of the OVN data plane during subsequent upgrades. OVN data plane downtime is serious as it will cause network disruption to all cloud VMs. This is an upstream OVN issue.

Charmed OpenStack supports OVN version 22.03 on Focal cloud nodes. It is recommended to upgrade directly from any lesser version to 22.03 by following the procedure detailed on the Upgrade OVN to 22.03 on Focal page.
