I am running a DHCP server on Windows NT 4 which will lease out around 50 IP addresses for notebook users. I would like to migrate the server to Linux. How can I smoothly do so? Will the new Linux DHCP server be able to handle the IP addresses that are already leased out to existing users? I assume that in worst case, I will ask all the notebook users using DHCP to shutdown their computers and then I will do the the migration and they will start up their computers again. But this is just the last resort.
After the WinNT is down, when can I resize the IP range for the Linux server? Will the Linux server knows which IP under the range 192.168.1.20 - 192.168.1.69 has been assign out by the WinNT?
