Change mobile data transfer

My APP is hybrid architecture, I transferred my test phone to a new phone, userdefault will be transferred, but the local storage of the front-end will not be transferred.

Both(userdefault&local storage) will be transferred when my colleagues transfer their personal phones.

My test case

  1. Same model mobile phone
  2. Mobile phones with the same OS version
  3. Switch from a small OS version to a phone with a large OS version
  4. Switch from large OS version to mobile phone with small OS version

The first three items are userdefault will be transferred, but local storage will not be transferred. The fourth item is that you will be asked to upgrade the OS version when transferring.

Does anyone know any relevant information? Or are there any settings enabled?
