Migrator - Android Backup Solution and ROM Migration Utility
It can backup/restore apps (including split APKs) with respective data and runtime permissions, system and Magisk data (including settings).
ZERO warranties, use at your own risk!
Install as a regular Magisk module (no reboot needed afterwards, though).
Alternatively, you can extract system/bin/migrator from the zip and run it as sh filepath (yes, no Magisk installation required).
The documentation is bundled.
Refer to migrator --help or M -h.
It can be exported to a file: M -h > file
If these executables aren't readily available (before a reboot), use /dev/migrator or /dev/M.
