  • Migrating from 0.2.0 to 0.3.0
    • The 0.3.0 release introduces a new, optional RangerAuthorizer provider as a NiFi Registry extension. If you wish to migrate from an existing ManagedAuthorizer backed by a FileAccessPolicyProvider, you will have to recreate all access policy rules in the externally configured Apache Ranger instance. Please see the nifi-ranger extension README file for full documentation on how to install and configure the extension.


  • Migrating from 0.1.0 to 0.2.0
    • The 0.2.0 release introduces new database configuration in nifi-registry.properties which provides more flexible options. When upgrading from 0.1.0, ensure that nifi.registry.db.directory points to the location of the existing H2 database to ensure it is migrated to the new database. Please consult the Database Properties section of the Admin Guide for further details of these properties.
