Hi Emilio Drago Foschi

All files are saved in your computer. Trados does not save any files on its own, so you transfer the files as you would normally transfer files between two computers.

If you transfer your Trados 2021 license from one computer to another, please deactivate the license from your computer, install the software on the new computer (please download the installer from your SDL account), and then activate the license on your new computer. 

To deactivate the license from the product please open Trados, and select Help - Product activation - and click on the Deactivate button

For a step to step guide  please click on the following link: https://community.sdl.com/product-groups/translationproductivity/w/customer-experience/1331.can-i-transfer-my-existing-license-to-a-new-computer 

If you have any questions, please let me know.

Kind regards,

Elisa
