Backing up settings for transfer to new watch

I read something a while ago that said there’s a certain folder or files that contain all the watch settings, data screens etc and this can be copied over to a new watch to save the initial setting up. Any idea which folder or files they are and would the replacement watch reflect the old watch exactly?

Could I just copy and paste the entire GARMIN folder?

Im specifically asking for Fenix 6 Pro to Fenix 6 Pro

Thanks all.
