We presently have the situation where Apache Ranger has been deployed along with Hadoop KMS with HDP2.2. Plan is to upgrade ti HDP2.4 and move way from Apache Ranger and Hadoop KMS completely.
In order to do so, we need to export the data from the existing setup to HDP managed Ranger and Ranger KMS.
To make the things slightly complex, present setup of Ranger and KMS are shared by multiple clusters and hence migration mechanism need to ensure that only approariate policies and keys are moved to the specific cluster's Ranger and Ranger KMS.
Given the above,what is the best migration mechanism to get the data from the 2.2 cluster to 2.4 cluster?
