Free upgrade from Windows 11 Home to 11 Pro using 10 Pro retail license

My current computer has an activated Windows 10 Pro retail license. I'm planning to replace my current computer by buying a new computer that comes preinstalled with Windows 11 Home, and then I understand I can use my 10 Pro license to upgrade to 11 Pro for free.

What's the most straightforward way of accomplishing this? The obvious approach that comes to mind involves two steps:

1. Reinstall Windows 10 Pro on new computer and activate with my existing retail license.
   
2. Upgrade new computer to 11 Pro for free through the settings.
   

Is there a simpler way of doing this without having to reinstall Windows 10? For example, would it be possible to somehow "trade in" my Windows 10 Pro license for 11 Pro? I'm fairly new to Windows licensing and am just trying to understand what is possible/best practice, with minimal effort.
