- If you are in a case of a multi-nic OpenStack VMs (see [kubernetes/cloud-provider-openstack#407](https://github.com/kubernetes/cloud-provider-openstack/issues/407) and [#6083](https://github.com/kubernetes-sigs/kubespray/issues/6083) for explanation), you should override the default OpenStack networking configuration:
```yaml
external_openstack_network_ipv6_disabled: false
external_openstack_network_internal_networks:
- ""
external_openstack_network_public_networks:
- ""
```
- Run the `upgrade-cluster.yml` playbook
- Run the cleanup playbook located under extra_playbooks `extra_playbooks/migrate_openstack_provider.yml` (this will clean up all resources used by the old cloud provider)
- You can remove the feature gates for Volume migration. If you want to enable the possibility to expand CSI volumes you could leave the `ExpandCSIVolumes=true` feature gate
