About Migrating Ranger policies

Migrating Ranger policies involves export and transform operations.

Firstly, the Ranger policies available in the source HDP clusters are exported and copied to the target cluster, followed by the transform and import operations. The export and transform operations are performed using the policy migration utility.

The Ranger Policy Migration utility files in the directory

ranger-<version>-policymigration consists of the following scripts:

  • env.sh

  • exportPolicy.sh

  • transform.sh

The contents of the policy migration utility would be copied to the source HDP cluster from which the Ranger policies are to be migrated. The output file from the transform process would be transitioned to the import operations. The import process consists of the import utility (Authzmigrator tool).
