Can a one-time change of addressing of the entire Elasticsearch cluster cause any problems?

Let's assume the scenario:

1. We have a working Elasticserach cluster on addressing (IP\_a, MASK\_a, GATEa).
2. We shutdown Elasticsearch services on all nodes.
3. We change the addressing of Elasticsearch nodes from (IP\_a, MASK\_a, GATEa) to (IP\_b, MASK\_b, GATE\_b).
4. We run Elasticsearch services on all nodes with new addresses.

Will Elasticserach not have problems?

Should be fine, as long as you make sure to adjust the [discovery settings](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-hosts-providers.html#modules-discovery-hosts-providers) so all the nodes can find the master nodes at their new addresses.

Many thanks for the information!  
I will probably test it tomorrow.
