This article demonstrates how to migrate from Elasticsearch to OpenSearch via a rolling restart.

This article describes how to use the Reindexing API to migrate data from an Elasticsearch to an OpenSearch cluster.

In this article we show you how to migrate your data from Elasticsearch to OpenSearch by using the Snapshot/Restore APIs.

In this article series, we will guide you through migrating from Elasticsearch to OpenSearch step-by-step. We start with checking some prerequisites and the question: Should you migrate at all? Spoiler alert: Yes, you probably should.

In this 3rd part, we are going to cover using commercial certificates from Let's Encrypt to bootstrap the OpenSearch/Dashboards cluster and therefore removing the need to generate self-signed CA.

We'll dive into the details of using cert-manager to create a self-signed CA. We will sign TLS certificates with this CA and deploy them to OpenSearch.

Using cert-manager in Kubernetes to generate (and more importantly automatically rotate) TLS certificates on OpenSearch and Dashboards.

In this article I will show you how to setup OpenSearch and Dashboards on Kubernetes using Helm Charts.
