Hi Guys,  
I have a version 1.x node red running on a ubuntu box. It uses a signal messenging node which I think won't work under node 2.x (the developer seems to have stopped working on this node).  
I'd like to move to node red version 2 for the rest of my flows. (try and keep stuff upto date etc)

Is there a way to install version 2 node red and not touch the old one and run the 2 together on different ports?  
Thanks  
Chris

> alternate-node-red-installer is not a node. It is, as it says, a template for an alternative way to install and manage Node-RED. Install globally using npm so that the nrinstall application is globally available. Should work on all platforms supported by Node-RED. The installer will install Node-RED to a folder and create a userDir sub-folder called data. That way everything is in a single place and can be easily backed up, copied, moved. It also allows you to easily have multiple instances of…
