By renaming an earlier Mac version of Pro Tools, you can then install multiple versions on the same drive – see:
2021.6 install on the same drive as 2020.9.1

The driver and firmware updates are usually backward compatible. I often use PT Prefs app to make a back up of my old prefs files for the old version, in case something gets whacky. And, most importantly, I always make a bootable clone using Carbon Copy Cloner before installing the new version.

Have you jumped between versions much to verify? |

That way, if I need to roll back, I know I have a clean set of prefs that are known to work with a specific version.
But I actually haven't had many if any issues jumping back and forth between versions. Of course, there are certain version jumps where there can be certain incompatibilities, like a version where they re-wrote the Workspace Catalog databases, and once updated, they couldn't be reverted. But on first launch of the new version, PT threw up a warning and suggested backing up the old database in case the conversion to the new format got corrupted. I don't really use Workspace Catalogs, so it wasn't an issue for me.

iLok
You can have all your Pro Tools licenses on one iLok
To use Pro Tools 10/11, you may have to
Deactivate Pro Tools 12 in the latest version of iLok License Manager (and later
Activate when needed)
After adding or moving a license, right-click on the iLok in the LH column of iLok License Manager and select “
Synchronize” – this takes a short while.
Once done, exit iLok License Manager, reboot, launch Pro Tools
