Multiple Subnets on one interface

Hello

We are changing our isp soon and we currently have a /28, I will be replacing the firewall with pfsense before we change isps. We will be given a new range which I would like to pre-setup on pfsense and have rules configured before the connection is "swaped"

Is it possible to have a /28 and a /25 configured on the WAN interface and DMZ interface ? the /28 would be removed eventually

are virtual ips on each of the interfaces the way to go ? I will be adding both networks to each server
