+  - All tiles in the "Files" category.
+  - The "Projects" tile in the "Management" category.
+- There are two options to change the link for the portal tiles:
+  - Use an admin account to access the portal's edit mode (on the bottom of the sidebar portal's menu).
+  - Utilize the UDM REST API to update the portal tile objects.
+- Update the hostnames for the OpenProject-Nextcloud integration using a functional admin user for both components:
+  - In OpenProject: *Administration* > *Files* > *External file storages* > Select `Nextcloud at [your_domain]`
+    Edit *Details* - *General Information* - *Storage provider* and update the *hostname* to `files.<your_domain>`.
+  - In Nextcloud: *Administration* > *OpenProject* > *OpenProject server* update the *OpenProject host* to
+    to `projects.<your_domain>`.
