Can I continue using Trados 2017 on one computer while upgrading it to 2022 on the other computer?

Question

I purchased Trados 2022 license, downloaded the program and deactivated Studio 2017 on my PC but not on the notebook . 
 Now I am trying to proceed and upgrade while remaining able to continue a 2017 project on my notebook. 
 QUESTION 1: Is this possible, or do I have to upgrade Trados on both machines at the same time? 
 I tried to click on the Upgrade (1) button below:

The following screen makes me afraid that if I continue I might lose extra activation for the notebook: 
 
 QUESTION 2: Will still be able to activate 2022 on the notebook after I click on "Process Upgrade"?

Hello Luca Tutino 
 You can activate Studio 2017 back on your PC as well. For Freelance Plus licenses you can process the upgrade without deactivating the current version. 
 When you click on Process Upgrade the 2017 license will be removed from your account and replaced with the 2022 license but you will be still able to use Studio 2017 until it gets deactivated for some reason (i.e: reinstall Windows). After the upgrade is processed and the 2022 will be available in your account you can also activate Studio 2022 on the same computers. 
 Thank you, 
 Sorin
