Today I had to migrate my IOT VM from a AMD64 system to a ARMv7. I ran it on a photon+docker host and now is installed in a Raspbian+docker in a raspberry.  
I simply moved the node-red docker volume with all it's contents to the new appliance so naively.  
Now when I enter nodered, I face the "Flows stopped due to missing node types (mysensorsdb)" hint.  
Inspecting the logs (in docker) I find the following messages:

```auto
> node-red-docker@1.0.4 start /usr/src/node-red,
> node $NODE_OPTIONS node_modules/node-red/red.js $FLOWS "--userDir" "/data",

```

So it's proven that my system is not platform agnostic.  
Is there a way to make it download/repair the required dependencies without rolling it all and re-importing the flows? That shouldn't be easy...

Connect into your running container and run: `npm rebuild` in `/data` to rebuild the native modules for the new architecture.

You _might_ need to run `npm install sqlite3` as well.
