To enable a successful integration, we must first conduct a systematic comparison of the feature sets in both the upstream and downstream operators. 
This task will:

• Catalog and categorize the core features of the upstream operator
• Document downstream-specific features, including customizations, extensions, and proprietary enhancements.
• Highlight upstream features that could replace downstream customizations (or vice versa) to reduce redundancy.

Outcome: A feature matrix detailing alignment opportunities, migration challenges, and potential consolidation paths.
