Elasticsearch is shown as the search engine despite OpenSearch installation

This article provides a solution for the issue where Elasticsearch is still shown as the search engine for Adobe Commerce on cloud even after installing or upgrading to OpenSearch.

Affected versions

Adobe Commerce on cloud 2.4.3-p2 - 2.4.5-p6

Issue

Elasticsearch is still shown as the search engine for Adobe Commerce on cloud even after installing or upgrading to OpenSearch.

Steps to reproduce:

Cause

Adobe Commerce is hard-coded to specify Elasticsearch7 as the search engine.

This is not to be confused with the installed version of the service. The application only recognizes Elasticsearch7 as the search engine but not OpenSearch, even though it uses the underlying OpenSearch service as the engine in the backend.
