Studio 2017 - 2021

Hello.

I have made an upgrade from Studio 2017 Freelance to Studio 2021 Freelance. For that purpose, I have deactivated my Studio 2017 license on my old PC and then activated the Studio 2021 licence on the new PC.

I then discovered that the Studio 2017 soft was no longer usable on my previous PC, what I would need for file, TM and termbases mananging purposes.

My question is: once deactivated in order to upgrade to Studio 2021, how can I still use my Studio 2017? Should I temporarily return o deactivate my Studio 2021 license?

Thank you in advance for answering.
