Upgrade from Cubase 8 to 13 on new Mac computer

I had cubase pro 8 on an old pc computer now I’m on new Mac how do I upgrade to 13

You login to your Steinberg account, buy the upgrade to 13 and install it on your computer?

Thanks for your reply

Sumnerlars… just curious. What Mac did you purchase? I’m contemplating an upgrade but haven’t pulled the trigger. Also, I used to use PC back in the day when there was so much more available in the Mac world. Now I’m seeing so many folks using PC’s again. I suppose things have leveled out between the two and probably doesn’t matter which platform one chooses. Anyway… Thanks.
