Hi, Is it possible to run 2 Elasticsearch instances like ES-2.x and ES-6 in parallel in the same Linux server as RPM installation. My concern is - if we install it as Linux RPM then the new one will override the existing one, but my usecase is to run in parallel as I need to maintain historical data with the old ES. It is known one, but just a ask. Can we migrate the ES index, Kibana dashboard from 2.x to 6 version? ---

You could try and have a look at using [Elastics with Docker](https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html). Usually I just download the tar.gz files from the elastic website when I want to run two different versions side by side. > [@](#): > > Can we migrate the ES index, Kibana dashboard from 2.x to 6 version? I am not sure how easy it is going to be, but have a look at migrating from [2.x to 5.x](https://www.elastic.co/guide/en/elasticsearch/reference/5.6/setup-upgrade.html) and then from [5.x to 6.x](https://www.elastic.co/guide/en/elasticsearch/reference/6.x/setup-upgrade.html) ---
