Subject Re: Upgrading from Solr cloud 4.1 to 6.2
Date Fri, 07 Oct 2016 07:55:54 GMT
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
