Really am I only one to wonder them spend zillion of hours creating tons of great new features (98% don't use), but this migration thing they don't have down at all...
Kevs, you sure doing a ton of complaining. Before was Imagenomic, now Adobe! Sounds as though you need to improve your understanding of the software.
Andrew will correct me if I’m wrong, but Adobe has been effecting many changes (Modus Operandi) of their suite of apps. Settings , workspaces etc are now centrally stored - the idea being that if you travel and log on to a third party computer , you can download yr ‘workspace’ and carry on as before, less your extra 3rd party plugins. Hence Chris’ post below.
You can create/delete workspaces but, AFAIK, they’re not stored on your computer. Plugins are purchased/installed and deleted via Creative Cloud / Adobe Exchange - in the new UXP format. Older ones are under Extensions(Legacy), not centrally stored.
The transition is a work-in-progress, not that it should affect you negatively -
IF, you had proper backups in place. Also some folder contents now remain hidden fm view - designed not to interfere with the syncing of settings.
e.g. try to access Lr’s User Presets in the Develop module from Finder - you won’t be able to, at least not under MaxOS Monterey. The only way is from Lightroom. Right click on the preset and ‘Show in Finder’ and you’re there !
For Lr backup, use this:

… Only thing I needed to do in order to launch them was to log into my Adobe Creative Cloud account on the Mac Studio. (Adobe uses a license-management scheme that imposes a limit of two simultaneous activations of its software per customer account.)
Note: to perform a MacOS migration the user must be logged into the same Apple ("iCloud") account on both the source and target computers.
