Need To Upgrade Os 10.7.5 To More Recent,, Will I lose my Kontakt libraries? Options

[Quetz]

Hi,
in order to use recent Kontakt libraries i need to upgrade Kontakt itself, and in order to upgrade Kontakt I will need to upgrade my Mac OS.

I'm currently on MacBook Pro, late 2011, 2.4 GHz intel Core 17, 16GB RaM 1333 MHz, DDR3 10.7.5, and it works like a charm.
I'm using Logic Pro 9 and Ableton Live 9, Kontakt 5.3.00.14 and mostly Kontakt libraries.

If I purchase and install a new OS (probably 10.8.something) , will I lose my softwares authorizations, and will I have to re-authorize my Kontakt libraries, plugins, etc, or can i proceed with no fear?

Any lucky or bad experience someone?

Thanks in advance !
Best
