+
+                        If configured in **configuration files**: they will be ignored and overrided by Azure Spring Apps.

+                        If configured in **Config Server files**, **command line parameters**, **Java system attribute**, **environment variable**: they need to be removed or you might experience conflicts and unexpected behavior.
