question on Migration assistent
From instructions for using the migration assistant
"In the example above, John Appleseed is a macOS user account. If you transfer an account that has the same name as an account on your new Mac, you're asked to rename the old account or replace the one on your new Mac. If you rename, the old account appears as a separate user on your new Mac, with a separate home folder and login. If you replace, the old account overwrites the account on your new Mac, including everything in its home folder."
I don't understand what the above means. I'm the only user on my old MacBook Pro and just want to transfer every thing to a new MacBook Pro. Do I need to rename a user account?
Also I'm tranfering from Time Machine backup to new Mac. Will everything be transferred? I.E. modem and wifi setting etc.
