Mark Outdated n8n Nodes on Canvas & Send Gmail Summary

This workflow serves as an add-on to the 'Check if workflows contain built-in nodes that are not of the latest version' template. It processes a list of outdated nodes from across your entire n8n instance, updates the affected workflows by renaming outdated nodes with a warning emoji (e.g., ⚠️) to prevent reprocessing, and positions a preconfigured latest-version node right next to it on the canvas for seamless swapping. This visual aid streamlines maintenance without disrupting existing connections.

Customizable settings allow you to choose the emoji/symbol for marking, toggle major-only updates or all versions, and decide whether to add new nodes to the canvas. A Gmail node sends a comprehensive summary listing all modified workflows, keeping your team informed.

Ideal for n8n administrators managing large instances with many workflows, it saves hours of manual auditing and updating. Use cases include regular instance health checks, pre-deployment verifications, or post-n8n updates to ensure compatibility and leverage new features efficiently.

Setup is straightforward: clone this and the parent template, configure the n8n base URL and Gmail recipient, then link via an 'Execute Workflow' node in the parent.
