Ok, as most of you are aware, I've got 110 tabs on my main Win10 PC standard install and I REALLY should sort this out! :slight_smile: So, what I'm thinking is, make a copy of it (somehow) and then edit the main so it just has the flows I actually use 24/7 to keep the house #IoT working and then r…

Simon, are you intending on running this on the same Win10 PC? If so, you can simply copy .node-red to .node-red2 and run it up at the same time using a slightly modified cmd line to launch it (to adjust the working folder location and the port number) and I would start the duplicate in safe mode u…

Surely it can't be that simple! Can it? :slight_smile:

Ok - off to read about starting in safe mode :slight_smile:

[image] cymplecy: I will enable safe mode BEFORE starting my new instance I will disable crictical tabs in new instance I will restart new instance in normal mode Right? :slight_smile: Pretty much spot on - though to clarify... After your copy is done... Fire up the new instance with --…
