Thanks Magnus & John. Yes certainly I will test it on a separate cluster first! Which is related to another question I have.
If I want to backup I can archive the directories on the nodes as described here: http://docs.basho.com/riak/latest/ops/running/backups/#OS-Specific-Directory-Locations But in order to verify the backup (or perform operations on the cluster in 'offline' mode), can I simply bring up a separate 5 node cluster and untar the backup files? (Probably not the /etc/riak directory, but the data and ring directories.) I want to do that, and then try adding a riak 2.0.6 node to the test riak 1.4.2 cluster and see if things are ok.
