I transferred my iPhone info to another iPhone, and all my notes didn't save/transfer

I had an iPhone, and I got a new one so I transferred all my data onto the new one. I checked all my apps, and nothing was different, everything saved correctly. Except I go onto my Twitter to check that and BAM! Enter your password. My password was on my notes. And all my other passwords for other important stuff. And all my April fools pranks ideas. And all my Bday present (for other people) stuff. EVERYTHING! My old phone was cleaned out, so I can't go on and get the notes from there. What can I do?

Type out all your notes onto your new phone. That's what I had to do. Took me ten minutes.

Recover your passwords with your email, it'll take long but unless you didn't wipe your old iPhone, you won't be able to recover it. You probably had them to save locally and not on iCloud so that's why they got lost, and didn't do this process with a full backup via iTunes.

If you still have acces to the old one, try sending it via message or airdrop to your new one.

Hi, you still have the chance to recover the notes from your old iPhone. Try a data recovery software, like FoneLab for iOS, it is free download and offers you to preview the lost data. If the software can find your lost notes, then you can consider to purchase the full version in order to recover.
