Replacement Router

[Bluebird4d]

I have a new Sky router coming today (same model). As we have 20+ devices connected to the Router, i would like to ideally keep all the devices connected to the router and make changing the router essentially just work as restarting the old one where everything just reconnects as normal once powered up. Can i do this by making a backup of current router on my IP login page and restoring it onto the new router? Or would i need to manually change the SSID and password back to the same as the old internet router? Would either of these prevent me from having to go back and manually reconnect every device to the router, as we have everything from TV's, Xbox's and computers to Ring doorbells, washing machines and tumble driers connected.
