I have questions:

- Can we upgrade version skipping such as Wallaby to Zed OR Wallaby >> Xena >> Yoga >> Zed?

- Is there any way to upgrade Openstack to a new version without host upgrade? Imaging that We have 1000 nodes as a Train version then we need to upgrade to Zed, it is too hard,

- Is there any plan to upgrade Xena(Ubuntu 20.04) to Zed(20.04).

Thank you. Regards
