Move index/data to new drive

Hello

I'm trying to figure out how to move the ES indexes from one drive to anther. Our current setup was not customized and all data is being written to a small partition and we'd like to move it to a larger one.

Is it just a matter of updating the elasticsearch.yml with the 'path.data:' and then copying the data to the new location?

I noticed that the indexes are located in:

/var/lib/elasticsearch//nodes/0/indices

Do I just replace '/var/lib/elasticsearch/' in the config file and copy '/nodes/0/indices'

thanx
