Recently I bought a 16" M2 Pro MBP 32gb/1tb. I used the Time Machine external drive on my M1 Mini 16gb/512gb and Migration Assistant to transfer everything to the MBP. It took about an hour. Four of my apps had problems though. The first time I ran them a window came up, said the app was corrupted, and it would be moved to the trash. Had to download those from the internet and install them. A few configuration problems too.
If I had it to do over I would install everything manually. I did not save any time. In fact, in total I spent more time trying to fix stuff and figure out what was not right than if I just did everything manually from the beginning.
