Currently all our indices are created daily with number of shards is 5(default). I would like to change number of shards to 1 for newly created indices. Can an index co exist with different number of shards.
logstash-2018-03-* with 5 shards
logstash-2018-04-* with 1 shard.
With the above configuration would I still be able search old and new data.
