+    ## Upgrading
+
+    If you are upgrading from <= 2.3.1 into >= 2.4, then you must run a migration to rename the `encrypt` column.
+    This rename was required for adding support for Rails 7.
+
+    You can use this migration.
+
+    ```ruby
+    # db/migrate/20220427113942_rename_encrypt_on_webhook_subscriptions.rb
+    class RenameEncryptOnWebhookSubscriptions < ActiveRecord::Migration[7.0]
+      def change
