We were using ELK cluster for observability log monitoring in our current project and now we are moving that to opensearch tool. So we need to copy data from current ECK cluster( indices data ) to Opensearch indices. Current Elastic search version being : V 8.8.2 Opensearch version : V 2.14.0

Currently in ECK stack, we use helm chart to push the data to Elasticsearch , Logstash version used is 8.8.2

FOr migrating the data we are planning to build a logstash pipeline to pull data from Elasticsearch as input plugin and opensearch as output plugin. Can help in getting correct version of logstash , to be compatible with both Elastic search and opensearch versions.

Also guide me with proper documentation to build helm chart.

Out of curiosity, why this move?

Why not keeping access to **all features** , like Vector Search, Security, Monitoring, Reporting, ES|QL, Canvas, Maps UI, Alerting and built-in solutions named [Observability](https://www.elastic.co/observability), [Security](https://www.elastic.co/security) and what is coming next 🙂 ?
