Thank you very much Paul. The pictorial explanation was very helpful, made everything clear. Thank you again. AFAIU, I can put my existing schema.xml and solrconfig.xml under conf/. I assume you also meant passing the paths to common schema and solrconfig.xml when registering a new core? My earlier try gave me some errors when I tried to do the same. I'll start afresh and let you know.
