How much time do you have to perform a cleanup ?
Mojave to Sequoia and Intel to Apple Silicon and migrated everything from Old to New
One Size does Not fit All
If the new computer is the Apple Silicon M1 / M2 / M3 /M4 Computer - would suggest Only Migrating the User Account and nothing more.
Some have had success and usually they are well seasoned veterans who are well versed in trouble shooting and have the time to do a cleanup
Others have been left with a mess when Migrating everything.
Issues that may have existed on the older computer will be migrated to the New Computer.
This would badly pollute the new Original and Pristine installation of the new OS.
Applications, extensions and Software Drivers may or may not even work on the new computer.
IMHO - it would be best to only install new application etc Directly from the Developer or the Apple Apps Store.
Due Diligence on New Applications and make sure they are Sequoia compatible and factor in the ARMs CPU of the Apple Silicon Computer
There is a relatively quick way to Start Over without this process Touching the Operating System ( Sequoia )
For Apple Silicon computer >> Use Disk Utility to erase a Mac with Apple silicon.
Using " Use Erase All Content and Settings "
