I need to replace the router, should I replace the Connection Unit also?

If you decide to replace the router, you can simply connect the Connection Unit Ethernet cable to the new router.

The associated devices and the saved settings will not be cancelled from the app.

You can check the correct connection of the devices through the operating LED (find more information about the LED in the questions in this section);
In case an error is detected, you will also receive the relevant notification through the IRSAP NOW App.
