Hi Eric Thanks for suggestion I was able to upgrade one shard one replica data from 4.1 to 6.2 through index upgrader, but the new problem is since we were using solr cloud with multiple shards(5) with some replication (3) so do I need to manually copy all index directory data for each shard upgrade and for each replica and place it in new index directory of solr 6.2 ?
This seems to be error prone as there will be 15 index directories thanks On Tue, Oct 4, 2016 at 8:35 AM, Erick Erickson <erickerick...@gmail.com> wrote: > the very easiest way is to re-index. 10M documents shouldn't take > very long unless they're no longer available... > > When you say you tried to use the index upgrader, which one?
