As both Jan and I mentioned, reindexing is _always_ the least error prone,
so please do that if at all possible And while you're at it it's a fine time
to make any tweaks like adding DocValues for fields you sort or
facet on, perhaps enable the new return stored fields from doc values
functiona
Thanks Jan for clarifying, I think I will pull all documents from data
source again as you and Eric suggested
Thanks

As Erick suggests, you should setup an empty 6.x environment,
create an empty collection with shards=5 replicationFactor=3
and then re-index all your content from your data source. Once that
is in, you can decommission your old cluster.

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 upgra
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? You'd
have to use the one distributed with 5.x to upgrade from 4.x->5.x, then
use the one distributed with 6x to go from 5.
Hello All
We are trying to upgrade our production solr with 10 million documents from
solr cloud (5 shards, 5 nodes, one collection, 3 replica) 4.1 to 6.2
How to upgrade the lucene index created by solr. Should I go into indexes
created by each shard and upgrade and replicate it manually ? Also
