Hello, We currently run Solr 5.4 as our production search backend. We run it in a master/slave replication architecture, and we're starting an upgrade to Solr 7.5 using a SolrCloud architecture.
One of our collections is around 20GB and hosts about 200M documents, and it would take around 6 hours to do a full dataimport from the database, so we'd like to upgrade the index and restore it to SolrCloud. I've successfully upgraded the Lucene 5 index to Lucene 6, and then to Lucene 7, so I think I have an index that can be restored to Solr 7. Do you know if it's possible to restore an index like this to a SolrCloud environment if I can get it into a directory that is shared by all the nodes? Thanks, Jack
