Transfer activation to a new laptop

I will get a new Mac very soon and I need to transfer my Parallels activation to the new machine.
How do I do that?

 

Hello @ErichN We can see multiple keys in your Parallels Account. So, we have sent you a private message. Can you please send the key which you are trying to activate in the private message. Thanks, Shathish

 

Hello @ErichN We have made the necessary changes, please try to activate now.
