Upgrade procedure from 0.12 to 0.13

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.

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 while the others are still available, or do all nodes need to be halted and upgraded at the same time?  I have backed up the /etc/riak directory to save the initial config data.  Are the 0.12 config files fully compatible with 0.13?
