Changing number of shards for new indices

Elastic Stack Elasticsearch
1

Hello,

Right now I have two nodes in my ES (part of ELK stack) cluster and 1 shard
for each index. I would like to change number of shards to two for future
indices. Can I do this by changing config file and restarting logstash?
Will it change number of shards for indices created after restarting ES?
Will it break existing indices?

Thank you!

It doesn't change existing indexes only new ones.
You can either do the setting change via the API or in the config, if you
choose the latter you will need a restart.
