+
+### Notes
+
+- The official React Router documentation explains [how to upgrade from v5](https://reactrouter.com/en/main/upgrading/v5).
+- Absolute paths for menu or settings links are still supported but should yield a warning.
+
+### Manual procedure
+
+Ensure that links added to [settings](/dev-docs/plugins/admin-panel-api#settings-api) or to the [menu](/dev-docs/plugins/admin-panel-api#menu-api) links using the Admin Panel API use relative paths.
