We're working on an application that is currently using java 11, spring boot 2.7 and elasticsearch 7.17.10.
We are migrating to java 17 and spring boot 3.1. Recently we stumbled upon a document that kind of suggests that with those changes, we will need to migrate to elasticsearch 8.x. However, we do not use Spring Data Elasticsearch.
We are not using Spring Data Elasticsearch, we are only using Elasticsearch Java Client. This article was also confusing to us a little bit. Does it mean that we can skip elasticsearch migration to version 8? (at least for now). It looks like we could.
