If you are changing the subnet mask on the BIG-IP, then it's probably going to require some layer 2 changes on the network device that it's connected to. So you'll need to coordinate the subnet mask change on both the BIG-IP and on the switch/router/firewall that it plugs into. Make both changes simultaneously if you can. Doing so will minimize downtime, but I see no way to avoid downtime completely.
