Hi,

I use a very old version of nodered (v0.20.07). I have many tabs and nodes for my smart home and everything works fine.  
Now I would like to update to the newest version. How can I do this without to loose all my nodes, settings and so on?  
I found that I need only to type " sudo npm install -g --unsafe-perm node-red": will this work? Will the new Node.js version be installed too?

Thank you!

Enzo

First a few questions before advice...

What hardware?  
What OS?  
Current nodejs version?

Your answers will help form a better response.

Ok, in which case I recommend you run the official installer script with `--node14` flag.

[https://nodered.org/docs/getting-started/raspberrypi#installing-and-upgrading-node-red](https://nodered.org/docs/getting-started/raspberrypi#installing-and-upgrading-node-red)

That will upgrade node-red & node js in one go

Before you do anything else make sure that your backups are up to date. You should have everything in your .node-red folder (assuming that is where your flows file is saved) backed up, except for the node\_modules folder which will be rebuilt.
