Hi @nialloc,
Thanks for reaching out to the Auth0 Community.
I understand you have concerns about safely migrating from Node 8 to Node 12 (latest).
To update your tenant settings to Node 12 on the Auth0 Dashboard, please navigate to your Auth0 Dashboard > Tenant Settings > Advanced and scroll down to Extensibility. Then set the Runtime version to Node 12. Once that is complete, don’t forget to press Save.
Migrating to Node 12 should not present any migration risks. See our Migrate from Node.js 8 to Node.js 12 documentation to learn more.
To safely migrate from Rules to Actions, please refer to our documentation - Migrate from Rules to Actions.
Hoped this helps!
Please reach out if you have any additional questions or need further clarification.
Thank you.
