Moving Kontakt on another (not so identical) system

Hi everyone,

perhaps silly question (newbie here): I'd like to move Kontakt library from a Mac to another Mac (samples will remain on an external drive).

Here my situation:

The "starting" Mac is an Hackintosh with Sierra 10.12.3 and Kontakt 5.6, and a lot of third party libraries (all the large stuff, i.e. the samples, is stored in an external USB3-SSD).
The "arrival" Mac is a MacbookPro with Sierra 10.12.6 and Kontakt 6.0.4 (a bit different version). I will obviously connect the same external drive with the samples, but I have also to transfer all the "libraries-installed-on-the-OS" of the Hackintosh to the MacbookPro's OS.

The question: is it possible? (Even between two non-identical Kontakt versions?)

Or should I re-install all the libraries one-by-one?

Thanks really a lot for your help!
