Solr/Lucene indexes are identical between SolrCloud and stand-alone, so yes you can move them around. I'm assuming your existing stand-alone is NOT sharded.
1> bring up a new SolrCloud collection with a single replica (i.e. replicationFactor=1). 2a> use the replication API fetchindex (https://cwiki.apache.org/confluence/display/solr/Index+Replication) to move the index from stand-alone to the new collection OR 2b> shut down the new SolrCloud instance and just manually copy the index from the stand-alone to the new core (actually I'd copy the entire data directory) 3> Verify your new collection "looks OK" 4> use the Collections API to ADDREPLICA to scale-out your SolrCloud instance, see: https://cwiki.apache.org/confluence/display/solr/Collections+API#CollectionsAPI-api_addreplica Best, Erick On Tue, Jul 5, 2016 at 1:00 AM, Preeti Bhat <preeti.b...@shoregrp.com> wrote: > HI, > > Can some one guide me on this? > > I have a standalone SOLR instance running as a service in Windows, I would > like to move towards the SOLR CLOUD, as it provides various benefits like DR, > scalability etc. I would like to use the same instance or core if possible > from the standalone instance to SOLR cloud.
