I have a new MacBook pro(with Lion). I used the time machine backup of my old MacBook pro(with snow leopard) to restore all my stuff. It worked well. The new MacBook pro has the same user account name as the old machine. The question I have has to do with using time machine with the new MacBook pro. When I set up time machine on the new machine what will happen on the time machine drive? Will it keep the old backups from the old machine. Or since both machines have the same name will it overwrite the old backups Thanks. .
