(Machine restarting NR)

Gee there is a substantial change in the `settings.js` file between 2.1.3 and 2.1.4!

I guess it is just a case of sitting down and going through them.  
But basically they are sectionalised in pretty much the same order?

(Nearly running)

Ok, so the `settings.js` can't exactly be copied from a `1.x` to `2.x` version - no? (or yes?)

I am also seeing this _message_:  
(sorry)

```auto
Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

```

Ok. I thought I had done that. (Moving on)  
I copy the `flows.json` and `flows_cred.json` file from their backup.

The `flows.json` has gone from `1.3 meg` to `2.2 meg` in size.  
??

# (machine now running NR) It worked!

(setting that line as you said.)
