-------------------------------------------------------------
So we need to have new cores up and running, and then install the new indexes
in them.
We could either do it like replication and use a new index directory (and use a
property file to redirect to that latest index), or we could try and make sure
that there is no open writer on the new core and then split directly into the
normal core index directory.
edit: we could also simply use the existing writers on the new cores to "merge
in" the new indexes (we just need to ensure that they are empty)
