Open Stack

Thank you for the extra info,

Going through those links today and the docs there. I found CentOS have
removed "pike" so I cannot apply any update with the same release of Pike
at the moment.

Can I follow this and go now to start upgrading to Queens?
https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/post_deployment/upgrade/major_upgrade.html

That guide does not mention anything like "you must first update to the
latest in the current release before performing a major upgrade".

thanks in advance
