Hi we have to upgrade elasticsearch from 7.5 to 8.X, the problem is that one of our clients uses APM and we dont have access to change the APM agents intalled on our clients machines, so we have to tell them what to do. -An 7.5 APM agent will be compatible with an 8.x APM server? ---

[Support Matrix | Elastic](https://www.elastic.co/support/matrix#matrix_compatibility=) is the definitive answer for this. You may also want to see [APM agent compatibility | APM User Guide [8.3] | Elastic](https://www.elastic.co/guide/en/apm/guide/current/agent-server-compatibility.html) ---
