Depends on your deployment tool. How did you deploy the 1000 nodes? Ubuntu Maas?

Oh.

It is terrible if we have 1000 ubuntu 20.04 nodes. :)

Ok. Then we are in the same situation. There is no official upgrade path yet. I’m on rocky 8 on yoga. And I’m not sure if it is intended / supported to jump from one Xena directly to yoga. But Ubuntu 22.04 will be supported in yoga:

Operating Kolla — kolla-ansible 15.1.0.dev99 documentation docs.openstack.org

Ubuntu Jammy 22.04¶

The Zed release adds support for Ubuntu Jammy 22.04 as a host operating system. Ubuntu Jammy 22.04 support will also be addeed to a Yoga stable release. Ubuntu Focal 20.04 users upgrading from Yoga should first upgrade OpenStack containers to Zed, which uses the Ubuntu Jammy 22.04 base container image. Hosts should then be upgraded to Ubuntu Jammy 22.04.

So you would need to upgrade to yoga first under Ubuntu 20.04, then upgrade your hosts to 22.04 and then upgrade to zed.

No, I'm not. 

I am using Xena on Ubuntu 20.04.

Hi,

If I’m not wrong there is currently no upgrade path from e.g. yoga to zed. At least for rhel / rocky. Zed requires rhel / rocky 9 and this is not supported in yoga yet. I guess if you are on train, you are running Ubuntu 18.04?

Cheers
