Bought V6 Upgrade. Question before I make a mistake[Solved]

I have both mac and win V5 license.
I’d like to upgrade the mac V5 to the V6 windows which I just purchaced.
As now only will use windows, I’d like to keep
the win V5 as is.
Any right way to upgrade?

Hi Toshiaki - Are your licenses academic or commercial? I can help! Thanks, Janet

Hi Toshiaki - send me your email address, and where you are located, I will send you your options. thank you, Janet Brock, janet@mcneel.com

Thanks! Just sent you email.

Just an update, so when upgrading the system just asks for the previous license number and the the upgrade license number.
So I was able to select mac V5 licese number first and use V6 to upgrade that.
Thanks.
