New iPhone 12 passcode
Just got new iPhone 12 - during setup process I set 4 digit passcode to same 4 digits as old iPhone 8 (poor decision looking back). In trying to transfer from old to new phone, it’s asking for old passcode but when I enter it it’s obviously saying incorrect as it’s matching the new passcode. What can I do? Can I change the new 12 passcode before continuing to set up new 12? Or can I continue setup (manually) then once complete, can I reconfigure to old iPhone 8 through iCloud? Any help would be appreciated.
iPhone 12, 15
