I think that would mean that the IndexReader and IndexWriter on that index are closed. 1. Do I need to stop SOLR search on both indexes before running the merge > command?

Any guidelines here are welcome. It is not very clear as to what you are actually trying to do. Why do you even need to merge indices? Are you creating your index outside of Solr? Just curious to know your use-case. -- Regards, Shalin Shekhar Mangar.
