Move from raspberry pi 3b to 4b

I need to move my installation to a raspberry pi 4b. I have a complete backup of my 3b operational system. I have correct hass.io and have installed it on the 4b. can I just restore the backup from the 3b and be up and running? If not, what files can I copy (I have samba copies of the entire config director) and what do I have to add manually?

Yes you can just restore the backup on the new Pi.
