RouterOS allows exporting and importing parts of the configuration in plain text format. This method can be used to copy bits of configuration between different devices, for example, clone the whole firewall from one router to another.

An export command can be executed from each menu (resulting in configuration export only from this specific menu and all its sub-menus) or from the root menu for complete config export and is available for CLI only. //
