Elasticsearch upgrade assistant

Elastic Stack Elasticsearch
1

Hi all,

We are trying to upgrade our Elasticsearch cluster from 7.17 to 8.X and found that its recommended to use Upgrade assistant for this. But we do not use Kibana in our cluster. The ES is acting as a search backend for some applications. How do we proceed in this case?

Hi,

If you don't use Kibana and therefore can't use the Upgrade Assistant, you can still perform the upgrade manually. Here are the general steps you would need to follow:

Check the breaking changes: Before you start the upgrade, you should review the breaking changes in the Elasticsearch documentation for each major version you're upgrading through. This will help you understand what changes you might need to make to your applications or configurations.

Regards

I would perhaps take the few minutes it takes to install kibana and leverage the upgrade assistant.

That will take less time than meticulously going through all the documentation, release notes, breaking changes etc. and probably increase your probability of a successful upgrade.

You can always remove Kibana afterwards.

Just a thought
