how to transfer notes from iPhone 8 plus to 14 pro max

On both iPhone's, make sure you're airdrop's are configured for “Everyone.”

Then, to transfer a note:

• Tap the share button in the top right corner of the note editor (or: swipe left on a note in the note list, then select More and then Share)
• Wait a second, and nearby iPhones, iPads, and Macs will appear at the top of the share sheet (note: those devices must have AirDrop enabled too)
• Tap your recipient’s device
• Your recipient will see a notification to receive your note. You must tap “Accept” to get it. If you tap “Decline,” the note will not be sent
• Once accepted, you're note will automatically open.
