Connecting Netgear Orbi to FritzBox

Hi,

My current home network consists of two Netgear 3700 wireless routers, configured identically, one used as an accesspoint. This works really well, I have one SSID and there are no problems moving from the one to the other router. 

The total configuration is as follows: Glass fiber modem -> FritzBox router -> Netgear main router Internet port.

The FritzBox is obligated by my cable company and is used to separate Internet and Phone signals. I do not use any other features of the Fritzbox, like the wireless router functionality.

As my Netgear 3700 routers are getting quite old and slow I want to upgrade. Netgear Orbi seems ideal for my situation.

My question is: can I connect the Netgear Orbi the same way as my current 3700 main router? That means I connect the output of the FritzBox router to the Internet port of the Orbi... ???

Thanks for your help,

Hans
