Legacy Authorized Users (NiFi Instance Upgrade)

If you are upgrading from a 0.x NiFi instance, you can convert your previously configured users and roles to the multi-tenant authorization model. In the authorizers.xml file, specify the location of your existing authorized-users.xml file in the "Legacy Authorized Users File" property.

Here is an example entry:

        <property name="Authorizations File">./conf/authorizations.xml</property>
        <property name="Users File">./conf/users.xml</property>
        <property name="Initial Admin Identity"></property>
        <property name="Legacy Authorized Users File">/Users/johnsmith/config_files/authorized-users.xml</property>

After you have edited and saved the authorizers.xml file, restart NiFi. Users and roles from the authorized-users.xml file are converted and added as identities and policies in the users.xml and authorizations.xml files. Once the application starts, users who previously had a legacy Administrator role can access the UI and begin managing users, groups, and policies.

The following tables summarize the global and component policies assigned to each legacy role if the NiFi instance has an existing flow.xml.gz:
