Just need some clarification with installation and upgrade of NR in ResPi:
According to the docs " If you have a version of Raspbian, or other Debian based install, such as Ubuntu , or Diet-Pi , that doesn’t have Node-RED already installed, you can install or upgrade using the Node-RED upgrade script command"
What if I have the default NR already installed by Noobs, do I have to remove it first before running the script, if so what is the best way to cleanly remove it? Would I have two instances of NR if I do not remove the default one first?
Where is the original NR that was installed by Pi located?
