A somewhat extensive NR "App" with Tasmota devices and MQTT control is to be transferred from one RPI to another one.  
The new/different RPI naturally has a different host name and a different IP address, but the Tasmota devices are of course set to the "original" values.  
The NR “App” also includes nodes like Dashboard (not yet Vers.2), file handling, tasmota, mqtt, ui-table. These nodes should ideally also be transferred.

What is the easiest and safest way to transfer the entire project automatically?

First, on the original pi, make sure all nodes are fully up to date (using Manage Palette).

On the new pi, install node red if you have not already done so, then copy the whole ~~.node-folder~~.node-red folder, except the node\_modules folder, from the old pi to the new one. In a command window, cd into the .node-red folder and run  
`npm install`  
which will install any additional nodes required by your flows. Then restart node-red and all should be well.

**[Edit]** Corrected typo

Thanks dear friend 😄 Will try and report back

... but ... here comes the first difficulty:  
This is my directory structure:

```auto
pi 
 .local
 node_modules
 .node-red
    images
    lib
    node_modules
 .npm

```

Which of them is that ` .node-folder` ?

The the .node-red folder

```auto
pi 
 .local
 node_modules
 .node-red <--- This one
    images
    lib
    node_modules 
 .npm

```

Sorry, that was a typo, it should have read .node-red folder. I have corrected it in the original post.
