Question : What is the best and safe way to change network IP range

Hello
I need to change the IP range of our entire network (DC, EXchange, FW, users desktops, DHCP, Vmware ESXi servers, router.. etc)
from 192.168.1.X to 10.X.X.X.
Some of the computers in the network are using DHCP some use FIX IPs.
What would be the best way to do it ? beside of downtime and manual configuration ?

Thanks !
