Decreasing shards

Elastic Stack Elasticsearch
1

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.

example: logstash-*

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.

Thanks

The beauty of using time-based indices is that you can change the underlying shard count over time through index templates, so the fact that indices being queried have different number of shards is not a problem at all.
