I've just realized that old and new clusters do use different installations, configs and lib paths. So the nodes from the new cluster will probably simply refuse to start using configs from the old zookeper.
Only if there is a way to run them with their own zookeper and then manually add as replicas to the old cluster, so old and new clusters keep using their own zookepers. -- View this message in context: http://lucene.472066.n3.nabble.com/SolrCloud-copy-the-index-to-another-cluster-tp4143759p4143769.html Sent from the Solr - User mailing list archive at Nabble.com.
