Thanks Eric! I'll look into that immediately - yes, I think that cURL would qualify as scriptable for my IT lead.
In the end, I found I could do it two ways... Either copy the entire solr data directory over to /var/solr/data on the new machine, change the directory name and the entries in the core.properties file, then start the already-installed Solr in cloud mode - everything came up roses in the cloud section of the UI - the new replica was there as part of the collection, properly named and worked fine. Alternatively, I used the command I mentioned earlier and then waited as the data was replicated over to the newly-created replica -- again, everything was roses in the Cloud section of the Admin UI... What might I have messed up in this scenario? I didn't love the hackish feeling either, but had been unable to find anything like the addreplica - although I did look for a fairly long time - I'm glad to know about it now.
