Today we prevent nodes from joining when indices exists that are too old. Yet, the opposite can happen too since lucene / elasticsearch is not forward compatible when it gets to indices we won't let nodes join the cluster once there are indices in the clusterstate that are newer than the nodes version. This prevents forward compatibility issues which we never test against. Yet, this will not prevent rolling restarts or anything like this since indices are always created with the minimum node version in the cluster such that an index can only get the version of the higher nodes once all nodes are upgraded to this version.
