Subject Re: SolrCloud - Shard splitting and re-sizing nodes

A couple of options:
1> physically copy the index over
2> (what I prefer) is to use the ADDREPLICA
command from the Collections API to bring
up a new node on the new machine as a replica
of one of your splits. It'll automatically synchronize,
and after it's done then shut down the original split.
