To me, inability to upgrade a large Riak cluster incrementally would be
a major factor against choosing it. The evolution of the protocols must
be constrained so that this is possible. Now is the time to work that
out, while the version number still starts with "0".

To the best of my knowledge, there are no changes between 0.12->0.13
that would prevent a rolling upgrade. That said, we have not tested
that specific use-case yet -- it's in the pipeline to be part of our
pre-release automated testing.
I'd recommend you'd try it on a QA cluster before doing it li
Great, time to buy 10 more macminis :)

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
I just used the new `riak-admin wait-for-service` command and some capistrano
magic trick to do a rolling restart of all my nodes in production after
installing the new debs. Worked like a charm.

I thought it's possible to do "rolling upgrade". ie, shutdown 1 node,
upgrade it, and reconnect the
node to the cluster.
otherwise you'd need 2X of the nodes in production.

I'm pretty sure that Baho would recommend that all nodes in a cluster should be
running the same version. An upgrade would probably require doing a full
database backup and a full database restore on a *new* cluster.

Hey folks,
What is the proper way to upgrade a cluster from 0.12 to 0.13? Our 4 node
cluster was originally created by installing the 0.12 rpms. Is the process
as simple as stopping riak on a node, installing the new rpm and
re-starting? Is it possible to roll through each node one at a time w
