I currently have ignition edge version 8.1.21 installed on a windows 10 machine. I may have to reinstall windows. I have already installed my licensing on this machine. If I needed to reinstall windows do I have to unactivate the Ignition licenses before reinstalling windows, installing ignition and uploading the saved gateway?
