Run multiple Elastic search instance in Linux environment

Elastic Stack Elasticsearch
1

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?

Hey! You could try and have a look at using Elastics with Docker. Usually I just download the tar.gz files from the elastic website when I want to run two different versions side by side.

I am not sure how easy it is going to be, but have a look at migrating from 2.x to 5.x and then from 5.x to 6.x
