I think [this note in the docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-bootstrap-cluster.html#modules-discovery-bootstrap-cluster-joining) describes the situation you're in, and also the solution. ---

Thank you @DavidTurner work for me 😃, NB : I had to do a "chown -R elasticsearch:elasticsearch /new datapath/elasticsearch" in addition to make it work. ---
