Hi Team, I have upgraded Elasticsearch Version from 2.x to 5.x. But the data path in old version is : data/elasticsearchCluster/nodes/0/indices, and that of new new version is : data/nodes/0/indices How can I copy the indices from Old version to new one..since the new version has additional feature like encryption. Note:- "path.data" in both cases is set to : /elasticsearch\_home/data Thanks, Gayathri ---

Elasticsearch upgrades what is needed. You don't need to touch physical directories. ---

> [@gayathri](#): > > I have deleted the data folder Do you mean that you removed all existing data? > [@gayathri](#): > > I want my existing indeces to be added to the latest version... But if you removed them how can you get them back? Did you read [Upgrading Elasticsearch | Elasticsearch Guide [5.2] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/5.2/setup-upgrade.html)? Worse case, you can reindex in a new 5.0 cluster from an old 2.x cluster with: [Reindex to upgrade | Elasticsearch Guide [5.2] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/5.2/reindex-upgrade.html) ---

As I said in the previous post, I have copied the data folder from old version. While starting the elasticsearch I was getting "location is not writable....." error message.. [ default index path in old version is : data/elasticsearchCluster/nodes/0/indices, and that of new version is : data/nodes/0/indices ] So I deleted the data folder, and tried to restart the elasticsearch, then the error gone and new index created on path:data/nodes/0/indices.. I have back up of my indeces on my old version's folder...PFB, the directory structure: [root@localhost elasticsearch]# ls -l total 32268 drwxrwxr-x 3 elasticsearch elasticsearch 4096 Jan 11 02:24 backup drwxrwxr-x 9 elasticsearch elasticsearch 4096 Jan 11 22:38 elasticsearch-2.3.3 drwxrwxr-x 10 elasticsearch elasticsearch 4096 Feb 20 01:57 elasticsearch-5.0.2 -rwxrwxr-x 1 elasticsearch elasticsearch 18012 Aug 9 2016 hs\_err\_pid32532.log [root@localhost elasticsearch]# ---

> While starting the elasticsearch I was getting "location is not writable....." error message It means that you don't have the write permissions on the data folder and/or one of its subfolders/files for the user who is running elasticsearch. This is what you have to fix before doing anything else. BTW why upgrading to 5.0 instead of 5.2.2? ---
