-Use `PermissionEvaluator` instead of `PermissionAuthorizer`.
+Accept `PermissionEvaluator` together with the deprecated `PermissionAuthorizer`.
 
 Apply the following to `packages/backend/src/types.ts`:
 
 ```diff
-- import { PermissionAuthorizer } from '@backstage/plugin-permission-common';
-+ import { PermissionEvaluator } from '@backstage/plugin-permission-common';
+- import { ServerPermissionClient } from '@backstage/plugin-permission-node';
++ import {
++  PermissionAuthorizer,
++  PermissionEvaluator,
++ } from '@backstage/plugin-permission-common';
 
   export type PluginEnvironment = {
     ...
     discovery: PluginEndpointDiscovery;
     tokenManager: TokenManager;
     scheduler: PluginTaskScheduler;
--   permissions: PermissionAuthorizer;
-+   permissions: PermissionEvaluator;
+-   permissions: ServerPermissionClient;
++   permissions: PermissionEvaluator | PermissionAuthorizer;
   };
 ```
