Before you upgrade to n8n 3.0
2 things in this workflow are removed in n8n 3.0. Fix them before you upgrade:
- HTTP Request Tool (legacy) in Activity Tool, Webscraper Tool: replace with HTTP Request node connected to the AI Agent's Tool input.
- AI Agent v1 (old agent modes) in AI Agent1 (v1.6), AI Agent (v1.6): replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).

| AI Agent v1 (old agent modes) AI Agent1 (v1.6), AI Agent (v1.6) | Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent. |
