Command: ‘rails generate adminterface:webpacker` Depending on your application’s configuration, you might need to perform some manual steps:

1. Change your ActiveAdmin config to use webpacker
  ```
  # config/initializers/active_admin.rb
  # ...
  #
  # == Webpacker
  #
  # By default, Active Admin uses Sprocket's asset pipeline.
  # You can switch to using Webpacker here.
  #
  config.use_webpacker = true
  ```

2. Migrate your custom javascripts and stylesheets to webpacker
  - app/assets/javascripts/active_admin.js -> app/javascript/packs/active_admin.js
  - app/assets/stylesheets/active_admin.scss -> app/javascript/stylesheets/active_admin.scss

3. Remove unnecessary sprockets files
  - app/assets/javascripts/active_admin.js
  - app/assets/stylesheets/active_admin.scss
