Nuendo - authorising different versions on 2 machines?

Sorry if this subject has already been discussed.

I’m currently running Nuendo 12 on my “old mac” (I can’t go any further than Mojave on it… so I’m stuck in N12).
I’m about to get my new Mac studio M3U and I’m going to install and authorise Nuendo 14 on it (I bought the update).

My question is:
Will I still be able to use N12 on my “old mac”?
Or will installing N14 on my new machine “break” the N12 authorisation on the old mac?

Installation and authorization are two separate things. You always authorize the most recent version you bought, and under this authorization, you can run any version which is equal to or lower than the authorized version.

So, authorizing and installing N14 will not break N12 on your other machine.

Thankyou

And you can authorize a maximum of 3 computer at any given time.
