asked on Transferring DHCP role from Win2003 to Win 2012 R2 with no downtime to workstations ?
Hi All,
I've got Windows Server 2003 in my Office building that I'm about to decommission and then resume the function in the newly created Domain Controller running Windows Server 2012 R2.
So may I know what's the correct steps before stopping the service on the old Win2k3 server and authorizing the new Win2012R2 server ?
Do I need to change the DHCP leasing period before the cutover or after the cutover to Win2012R2 ?
What's the impact for the user ?

ok, I've successfully migrated the DHCP using the guide above.
but somehow only the Wireless LAN can talk to the new DHCP server not the Ethernet cable network. Is this because of the DHCP forwarder or helper issue on the Switches ?

yes it is already fully imported.
I suspect that there is something stopping or not passing through the DHCP packet between the different VLAN or IP address subnet.
How to check this on the server side to see if this is a network device issue not a server issue ?
