Okay so instead of going through the manage palette I uninstalled node-red-contrib-alexa-remote2 and installed node-red-contrib-alexa-cakebaked via the CLI by doing this in the .node-red directory:
npm uninstall node-red-contrib-alexa-remote2
npm install node-red-contrib-alexa-cakebaked
I did NOT have to change any of my nodes or config!!!! Warning have not really tested this yet but everything appears to be okay. AM NOT RESPONSIBLE FOR BAD THINGS (well not THESE bad things).
edit1: Make a backup first before doing anything!!!
edit2: restart Node-RED afterwards for the changes to show up. (thanks @cjkeenan!)
