Do I need to deactivate the 2019 license before installing 2021 as upgrade?

Recently I purchased Upgrade to 2021 via Proz TGB. Before installing these 2021 Studio and MultiTerm, I have a question.

Do I need to deactivate 2019 license first before installing 2021? Or is it okay if I install the Studio/MultiTerm 2021 while 2019 is installed?
