when I copy a flow from one machine to another I follow these steps:
test system with customised and tested configuration node ( home assistant in this case)
live system export a flow - sub flows and configuration nodes are included - save to file or clipboard - import flow to new tab on the test system.
At this point in time I have a test system with two configuration nodes for home assistant. One is working with one connected node and the other is not working with around 50 connected nodes.
How to I change all the nodes to use the working configuration - currently I open each node and change the server - not the most efficient, and I'll have to repeat that if I want to bring the updated flows back in to my live system..
