Before you upgrade to n8n 3.0
1 thing in this workflow is removed in n8n 3.0. Fix it before you upgrade:
- AI Agent v1 (old agent modes) in Orchestrator (v1.7), Headlines Writer (v1.7): replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
- Also check Slack Trigger requires a signing secret on the Slack API credential.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).

|---|---|
| AI Agent v1 (old agent modes) Orchestrator (v1.7), Headlines Writer (v1.7) | Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent. |
