> During the prerequisite checks, any of the existing checks that prevent the
> upgrade from starting based on stack distribution or host availability will
> need to be modified to exclude unhealthy hosts.
> A new prerequisite check will also be created to warn the administrator that
> there are hosts which are in maintenance mode and will not be upgraded. This
> warning is for informational purposes only and will not stop the upgrade.
