Hello all - I am looking do to an Isilon cluser "refresh" from X200 nodes to X210 nodes. Currently there are four X200 nodes we would like to migrate to four brand new X210 nodes and eventually move the original X200 nodes to a DR site. I was looking at Article Number 000304058, "OneFS 6.5 and later: How to replace nodes in a cluster with nodes of a different type using SmartPools?" which seemed promising.  However, I noted that one of the requirements is that the nodes be of different node types.  I'm assuming X200 to X210 does not qualify.  If they do not qualify, can anyone point me in a direction for doing this "migration"?  Ideally I would like to be able to add the new nodes into the cluster, transition the data to the new nodes and smartfail out the original nodes. One point not mentioned in that article - would I need or want to renumber the nodes so that there is a "node 1" once all is done? Thanks in advance for any suggestions or insights.
