Before you upgrade to n8n 3.0
2 things in this workflow are removed in n8n 3.0. Fix them before you upgrade:
- AI Agent v1 (old agent modes) in AI Agent (v1.8): replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
- SerpApi (Google Search) in Google Search: no direct replacement: call the SerpApi REST API with an HTTP Request tool, or use a verified community node.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
