I have a small question.
For the pre-installed AHV nodes with CVM, could we able to upgrade only AOS version before creating cluster? Because the AHV version already same version as our desired version, but AOS version is not same. I know the way to re-install AHV and AOS by Foundation VM, but the way takes long time. Therefore I' d like to update for only AOS if we can.
In the other hands, we can upgrade AOS from Prism UI so I will able to upgrade AOS after creating a cluster. So this question is just for my reference.
My environment is below
AOS : 5.15.2 (want to upgrade to 5.15.5)
AHV : 20170830.434

You pretty much answered the question yourself:) You can use Foundation to re-image the node to the desired version. That is the manual way for a node that has not joined a cluster yet.
When you expand a cluster (join a node to an already formed cluster) the cluster expansion workflow will detect that the node is on a different version and will update the CVM on the node to match the version of the cluster.
