You must exclude them, but that can be done with either stick.

That's the way I recommend doing it so you don't end up with a long list of generic node information in the popup when you edit your existing Indigo devices to match them up. However, if you are super careful to document exactly which device you include (in what order) then you could probably do them in batches by carrying the stick around. Not devices that need to be included with encryption (locks, etc) because those have to be included from Indigo directly.

I believe there is a backup/restore Windows app that Aeotec supplies that might do it (someone who has done it is welcome to chime in), but you can't do it from your Mac/Indigo.
