need some help in upgrading elsticsearch 1.7 to 5.5 in single VM enviroment
I want to upgrade my production elasticsearch 1.7 version to 5.5 version
-> I found out the below links https://www.elastic.co/guide/en/elasticsearch/reference/current/reindex-upgrade.html
Here we have 2 options:
I wanted to go with Upgrading with reindex-from-remote but issue what faced is we have only one VM.
I will not able to install new elasticsearch-5.5 because we have 1.7 installed .
Can you please suggest me how can I upgrade elasticseach from 1.7 to 5.5 without losing my data in single VM?
