Can I share the same Megascan Libray across different version of Quixel Mixer?

I just got a new dev laptop and is migrating all the stuff from my old laptop.

I use Quixel Mixer 2020.1.1 all the long and it is a complete offline installer, bit I have 20+ GB of Megascan lib and my project folder. I’m also interested in the last Mixer built as well as it suport multiple material and opacity/emission layer.

So my question is:

  1. Should I install both my legacy version of Mixer (2020.1.1) and the latest built of Mixer and share my on going projects?

  2. Can both version of Mixer share the same Megascan lib?

  3. Can I point both version of Mixer to my t0-be-migrated Megascan lib at a new drive location?

Thank you very much~!!!
