Well it sounds to me that there are three primary considerations. Riak_core, Riak_kv and bitcask (assuming you are using that backend). If either of those change in some incompatible way you could end up doing damage to your data. I dunno, sounds possible to me. That said, rolling upgrades would be ... desirable. Personally I would not do it unless Basho said it was kosher.
