## How to specify allowed migration paths
- You can specify migration rules (whether an upgrade from a version to a version is allowed or not) by creating a migration_paths.json file in your build directory
- E.g. : Suppose builds for "guacamoleb" devices are stored at "/mnt/rom/builds/full/test/guacamoleb". The file "/mnt/rom/builds/full/test/guacamoleb/migration_paths.json" should then have contents like:
```json
{
"9":[9,10],
"10":[10,11]
}
```
- The contents should be read as: Upgrades from major version 9 to major version 9 and to major version 10 are allowed. Upgrades from major version 10 to major version 10 and to major version 11 are allowed.
- If file is not available or there is no entry specified, it is assumed that same version upgrades are allowed (e.g: "9" to "9" is an allowed upgrade)
### ONLY for LineageOS 15.x and newer
If you are willing to use this project on top of your LineageOS 15.x ( or newer ) ROM builds, you may have noticed that the file named `build.prop` have been removed inside your ZIP file, and has been instead integrated within your `system.new.dat` file, which is basically an ext4 image ( you can find out more here: https://source.android.com/devices/tech/ota/block ).
