Are different Trados Studio versions available for network licenses?

Is it possible to use Trados Studio 2017 and Trados Studio 2019 for network licenses on different PCs?

To upgrade to 2019, we need to change PC from 32 bit to 64 bit for the upgrade requirement, but it takes some time for all network licence users to change PC.

Can some network license users use Studio 2019 while the other network license user still uses Studio 2017?
