is it possible to update a signoz-collector version which only acts as an agent and isn’t the one writing to clickhouse (i have a separate layer of signoz collectors doing that). Basically can the new signoz collector act as an agent successfully while keeping SigNoz on an older version on the collectors that write to clickhouse + all the app containers (query-service etc)?

You want to update version of the OtelCollector Agent (OtelAgent) in K8s-Infra chart, is my understanding correct?
If so, yes. It is possible to different version of OtelCollector for K8s-Infra chart, provided that there is no breaking change affecting the previous original version.

my setup is a custom one on ECS. One set of collectors act as agents on each EC2 node which forward to another cluster of agents which write to backends, one of which is the signoz collector agents which write to clickhouse

Interesting. It would be nice if we could catch up some time later to see how it is all working for you.
Coming back to your question, yes, the answer would remain the same. SigNoz OtelCollector should be compatible with other otel-collector versions provided that there is no related breaking change(s). @Srikanth Chekuri should have more idea on the same.

If you can share the version of the agent and the main collector that writes to ClickHouse that are currently used and what you want to upgrade to, that will help answer the question. There maybe some incompatible changes, but that depends on the version and the components you use.

0.55.3 for all collectors. Thinking of going to latest release to possibly fix memory bugs in prometheus components

It should be fine. Can you share what components you are mainly using? From the signoz collector side, there weren’t significant changes.
