Move Davinci Resolve to a new computer?

I'm wanting to move my Davinci Resolve Studio to a new computer.
It is activated on my Desktop computer.

The code came with my p4k and p6k - but I don't know which code I used as I had 2 codes actually (one from each camera).

I want to find the code before "deactivating" it in DR 17.

What happens when you "deactivate" it in DR17? Does it email you your code?
If they don't tell you what code you are freeing up... then how do you know which one you deactivated if you have multiple codes?

You're overthinking this.

Deactivate, then use one of the codes (doesn't mater which) on the new system.

it will not mail you your code, so make sure you have the code at hand when you try to licence the new machine

you may have to play wack-a-mole with licence codes, but that's not the end of the world, only a mild annoyance if you have the codes at hand

show stopper if you don't tho
