Before you upgrade to n8n 3.0

3 things in this workflow are removed in n8n 3.0. Fix them before you upgrade:

  • AI Agent v1 (old agent modes) in AI Agent (v1.7): replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
  • HTTP Request Tool (legacy) in HTTP Request1: replace with HTTP Request node connected to the AI Agent's Tool input.
  • SerpApi (Google Search) in SerpAPI: no direct replacement: call the SerpApi REST API with an HTTP Request tool, or use a verified community node.
  • Also check Gmail Trigger below v1.4 runs as v1.4 (drafts skipped, max emails per poll).
  • Also check AI Transform: Automatically migrated to a Code node on upgrade, keeping the generated JavaScript. You can no longer add new AI Transform nodes.

Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).

Removed in 3.0Replace with
AI Agent v1 (old agent modes)
AI Agent (v1.7)		Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
