> When there is a new feature in a new software, the new feature may not work 
> correctly with the old software.  In such case, rolling upgrade should be 
> done by the following steps:
> # disable the new feature,
> # upgrade the cluster, and
> # enable the new feature.
> We should clarify it in the documentation.
