How to transfer data via adb?

Question

Android

Good afternoon!
It is necessary somehow through adb to transfer data from one smartphone to another, I tried it through a backup, but for some reason it weighs a maximum of 300 mb and does not transfer anything
Tried
adb backup -apk -shared -nosystem -obb -f adb.ab
How to write a command correctly or maybe there are some other ways to transfer data on the old device)?
And is it possible to transfer data as in applications, not backup to a PC and then restore it, but immediately transferring data to a new smartphone?
