1 year ago I think what you might want is an OTel Collector (https://opentelemetry.io/docs/collector/). You can set it up to scrape Prometheus data, and (even though I haven't tried it) I think you should be able to scrape from multiple Prometheus instances (see the Configuration section).
On an unrelated note: You might be interested in joining the CNCF Slack. There are a few channels dedicated to OpenTelemetry as well as the collector, e.g. #opentelemetry or #otel-collector, where you might get an answer a bit quicker than here. Opening an issue here is more for when you have identified a problem with the project or want to propose a feature that is not yet available. For help in setting up OpenTelemetry, I would refer to the docs or the Slack channel linked above.

What are you trying to achieve?
I am trying to ingest all the metrics scrape by two prometheus instance into opentelemetry. Any document will be much appreciated.
What did you expect to see? All the metrics is from prometheus instance collected and sended to the exporter.
Additional context. NA
