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.

 

Is this Amazon Store selling Windows 10 Pro keys legit?

I have no idea if it is, especially with the weird name it has. Could you please confirm if this is a legit store or should I avoid it?

Can I buy OEM licenses from Amazon to Install on a Computer I intend to Sell?

I am intending to build custom spec computers for clients and sell them.

I also plan to do everything by the book and want to ensure I have understood the use of OEM licences correctly

My understanding is an OEM licence can be used if the intention is to sell the computer and not for personal use.

I also read there are authorised sellers for the licences and Amazon is one of them (although i could not see it in the list of UK resellers when i checked the website:

Would I be correct in saying I could purchase Microsfot Windows & Microsoft Office OEM licences from Amazon for use on a new computer build that I plan to sell?
