Xin chào Nguyen Nam Anh,
Under Microsoft licensing terms, GGWA licenses are fundamentally non-transferable. The instant they are activated, they become permanently bound to the hardware signature of that specific device. There is no supported mechanism or exception to move them to older devices, even in the case of a deployment error.
You can easily resolve this compliance mismatch by strategically deploying the Full Packaged Product licenses you recently purchased. Since the GGWA licenses are already locked to your newly purchased laptops, you should simply leave them in place. The new laptops are fully compliant and legally licensed by those GGWA activations.
You should then apply your new FPP licenses to the older machines currently running Windows Home. Unlike GGWA, FPP licenses are fully transferable. Deploying them to your older hardware successfully upgrades them to Windows Pro and fulfills your legalization requirements. This approach also protects your investment, as the transferability rights of the FPP licenses will allow you to legally move them to new hardware when those older devices are eventually decommissioned.
