Hey,

I think answer would depend a bit on way of how openstack was deployed.

One of things I would check first, if your OS is compatible with project testing interface for each release:

https://governance.openstack.org/tc/reference/project-testing-interface.html#extending-support-and-testing-for-release-with-the-newer-disto-version

Then another thing, if you're relying on system packages to install OpenStack, you need to ensure that RDO project has built them for corresponding EL / OpenStack release:

https://www.rdoproject.org/rdo/release-cadence/

If you're to use any deployment tooling, they may have their own compatibility matrix, for example

* OpenStack-Ansible: https://docs.openstack.org/openstack-ansible/latest/admin/upgrades/compatibility-matrix.html

* Kolla: https://docs.openstack.org/kolla-ansible/latest/user/support-matrix.html

Hope this helps:)

Hi,
For OpenStack compatible check, how should we know the connection with base OS?
Example;
If the machine support RHEL9 and OpenStack Wallaby, can we say it is compatible to the newest OpenStack than Wallaby?
So it should be no problem with Xena, Yoga, Zed, Antelope and Bobcat?

Or please kindly let me know where can find the similar document?
Thanks.
