Hi @KlausRossler
According to your description, the old machine included Office Home & Student 2019 as a part of the purchase instead of being added by you. It is an OEM license that stays with the old machine. It cannot be transferred.
Thanks for your understanding.
If you purchased Office products separately, after binding your Microsoft account to the Office license, Office will be displayed in My account > Purchased apps. You only need to uninstall Office on the old device and install it on the new device to complete the transfer.
