Hello! I’d like to know if pmm-agents v3 are compatible with pmm-server v2. I couldn’t find anything about this in the documentation. Could you provide some information? Thank you.

Hi,

No, PMM Client v3.x binaries are not backwards-compatible with PMM Server v2 because of the breaking changes in API between the versions.
