Running two firewall devices

A site at the moment has a bog standard fibre device from the ISP which has services such as DNS, DHCP, firewall etc. I am upgrading this to a full enterprise Draytek firewall so we can get all the above features and with the added security and IPSec VPNs however never installed one from fresh, only configured existing ones.

My question is, is there a reason why I can't keep the existing device in place, disable the services on it so its just acts as a router and then place the new firewall off that one?

So it'll go Fibre -->-- Old Device -->-- New Draytek -->-- Internal Network
