Hi Shani, There isn't a SolrCloud way to do it. A proper 'clone this collection' feature would be a very useful thing.
However, I have managed to do it, in a way that involves some caveats: * you should only do this on a collection that has no replicas. Add replicas *after* cloning the index * if you must do it on a sharded index, then you will need to do it once for each shard. No guarantees though All SolrCloud nodes are all already enabled as 'replication masters' so that new replicas can pull a full index from the current leader. We're gonna use this feature to pull our index (assuming single shard): http://<your-new-node>:8983/solr/<new-collection>_shard1_replica1/replication?command=fetchindex&masterUrl=http://<your-old-node>:8983/solr/<old-collection>_shard1_replica1/replication This basically says to the core behind your new collection: "Go to the core behind the old collection, and pull its entire index". This worked for me. I added a replica afterwards, and the index cloned correctly. However, when I did it against a collection that had a replica already, the replica *didn't* notice, meaning the leader/replica were now out of sync, i.e: Really make sure you do this replication before you add replicas to your new collection. Hope this helps.
