New Mac New OS - PT Version?

[mrgroovy]

My 2011 iMac Thunderbolt port gave out. I was running Sierra (the highest I could go) with PT 2018.12.0.
I just purchased 2018 Mac Mini i7 with Catalina 10.15.7. I am thinking I want to run a clean fresh install of all software including PT without cloning my hard drive from the old iMac.
AVID states my PT for my Mini and Catalina are Pro Tools 2019.5 - Pro Tools 2020.11
If I load 2019 or 2020 on the Mini will I have any issues in opening up my saved sessions created in PT 2018.12.0?

Old sessions should open and run fine. I Agree that a fresh install is much preferred over any updating as you have changed a lot of hardware. If you do go to PT 2020.11, it will open in the new Dark mode by default. If you don't like it, just open Preferences and select Classic mode and restart PT.

To add to this - when installing the third party plugins make sure to have fresh/clean/latest versions of all plugins. Hopefully everything is signed so there won't be any problems when installing.
