iPhone migration added in iOS 12.4

I have been using iPhone 3GS since 3GS and it was so easy to move the hardware as I used itunes "soul backup" every time I changed the device about once every 2 years.

However, one day after "Local Backup Encryption" occurs, every time you repair your iPhone, you will have various problems and you will get mental damage /

Apparently this password is correct.
I did not check my password when I backed up, but I do not remember my password when I recovered it.
I did not know it was an encrypted backup, and after selling it, I sold it and recovered it.

I was wrestling with iTunes for an hour last night.
After the shower, I started to restore the backup / new phone at about 11:30 am. But thanks to itunes, I got a sweaty and nervous back.

Subject: Before encryption backup

Make sure I know the password
Put all your passwords

I can not do it.
I did an encrypted backup with the new password.

I want to recover my new phone.
ITunes is wrong password ..

I am experiencing the depressing feeling of the underbelly duck
The iPhone suggests that you can do something if you close the old machine, like the toad of the mouse.

The process is simple.
You do not have to put a password in the middle.

Both devices are iOS 12.4, and instructions for that feature will appear when first enabled on a new device (or fully initialized).
If you leave the original device near the device to be recovered, the encrypted pattern (?) Will be displayed on one side and the pattern will be transferred to the original on the other side as if scanning the QR code.

It seems to use Bluetooth communication for transmission, but data communication took about 10 minutes.
The original device was the iPhone 8 64GB, it only contains pictures, and the app is a light use environment with only the katok.
There is no such thing as a game or music / video that takes up a lot of space.

Immediately after the recovery, you should go through the process of downloading third-party apps from the App Store like any other recovery method. After the restoration, I confirmed that the picture was all in, and I got up and confirmed that the Katok conversation history entered normally.

When you finish the migration, the above screen appears on the source device.
Do not forget that you need to "Remove from account" as well as "Clear all content and settings" before you leave your iPhone,
