Yes, remove the entire <indexDefaults> and <mainIndex> nodes and add their contents in a new <indexConfig> section. Make sure to remove duplicate nodes. Look at an example solrconfig.xml shipped with Solr 4.x to see what is supposed to be inside the <indexConfig> section (note some of those configurations might be commented out in the example config). > >> Step 7: Make a list of existing external library dependencies referred in >> solrconfig.xml > > Where do I find those? Does your Solr installation use any custom components? Basically is there a mention of any class that doesn't start with solr.XXX or org.apache.solr.XXX packages? During deployment, does your solr installation contain additional jar files in your servlet container's lib directories? > > And finally under: > >> What will happen to existing Solr Index? > > How do I know have "Classic Solr" or "SolrCloud"? With 3.x you basically had what we call Classic Solr i.e. a non-SolrCloud deployment which does not need a ZooKeeper installation. On upgrading you can continue in the earlier non-cloud mode or switch to SolrCloud to take advantages of its new features. > > > > -- > View this message in context: > http://lucene.472066.n3.nabble.com/Steps-to-take-when-upgrading-from-3-5-0-to-4-2-tp4072634.html > Sent from the Solr - User mailing list archive at Nabble.com. -- Regards, Shalin Shekhar Mangar.
