Hi Channel,
We are planning to upgrade Elasticsearch opensource 7.9.1 to 8.4. while upgrading we noticed multiple data disk path deprecation warning . Could anyone help us how we can proceed further.
FYI, Elasticsearch cluster has 3 Master node, 10 Data nodes and 14TB data !

You cannot directly upgrade to 8.x, you have to upgrade to 7.17. Follow [the documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-upgrade.html). Multipath are deprecated since 7.13
