If the upgrade involved a database migration: 1. Check the feature documentation and release notes to see if there are any manual changes you need to make. 1. Run `n8n db:revert` on your current version to roll back the database. If you want to revert more than one database migration, you need to repeat this process. ## Windows troubleshooting If you are experiencing issues running n8n on Windows, make sure your Node.js environment is correctly set up.
