+## Migrating to Data Prepper 2.0
+
+Starting in Data Prepper 1.4, the trace processing uses Data Prepper's Event model. This allows
+pipeline authors the ability to configure other processors to modify spans or traces.
+
+To provide a migration path, Data Prepper 1.4 introduced the following changes.
+* The `otel_trace_source` has an optional parameter `record_type` which can be set to `event`. When configured, it will output event objects.
+* The `otel_trace_raw` replaces `otel_trace_raw_prepper` for event-based spans.
+* The `otel_trace_group` replaces `otel_trace_group_prepper` for event-based spans.
+
+In Data Prepper 2.0, the `otel_trace_source` will only output Events. Data Prepper 2.0 also removes
+`otel_trace_raw_prepper` and `otel_trace_group_prepper` entirely. To help migrate to 2.0,
+you can configure your trace pipeline using the Event model.
