Hi,
I wondering how to do it.
I must do a Clean install, but I am worried about re-settings of all applications that I installed on my account.
Is there any option that will be able to restore from backup all applications (or those that I select), including their settings?
Will Time Machine handle it and recover data (make on Catalina) on the new system (Big Sur)? or maybe use any third-party backup utility?
Personally, seeing that a third-party App like "Clean my Mac" was installed and used to make space - I too would do a Wipe and Clean install. That App ( Clean My Mac ) is considered as very very bad for causing big problems on macOS and even delated things required by the Operating System.
Suggest to uninstall Clean My Mac as per the Developers Instruction and check how the computer functions without it. Then try this link to see what is using the space on the computer.
If still not satisfied How to Reinstall macOS from Recovery Mode

It looks like one what's to do a Clean Install of Big Sur because something went wrong in the upgrade process ? Was it an Application or the OS itself that has prompted the desire to clean install ? Perhaps it can be fixed instead of a Wipe and Clean Install ! ?
It's only my sugestion to make clean install.
I don't have much free space to upgrade. Had only 10G free space on disk.
I trying remove everything what i can find in Google.
I use third-party soft utility to clean my mac - still have (wow) +1G more.
Everything get something called " Other " in "About mac -> Storage "
That is what i I have decided to make clean install.
and I hope to this step to unlock my mac from high CPU/disk/ram usage even if I do nothing :|
If you do a clean install, only to them migrate everything, then you are wasting your time. The migration will undo the benefits of the clean install.
Migrate only the user accounts, and NOT applications, settings or other files.
@ Luis Sequeira1 makes a very important point about Migration Only User Account. A Full Restore will totally undo everything the clean install has done. Namely a pre-exiting problem reintroduced from the Time Machine Backup.
Ah, this is the black scenario what @luis wrote.
I will spend many hours reconfiguring it all again.. oh all Saints - why..
Clean install Big Sur and restore App+Settings from backup
