Im glad you managed to get it working in a different device ..  
A while back i remember sharing a video i found on the net that describes how they updated the IoT2050 to the latest versions for Node-red and Node-js .. personally im not familiar with the device but here is the [post](https://discourse.nodered.org/t/reading-a-mdb-file/65659/17) in case you want to ask the person that has it if everything is running smoothly.  
Also you can try asking on the Siemens if they have any official update procedure.
