This simple process describes the how to migrate a DHCP
reservation list without having to migrate the entire scope.
1.
Export
the DHCP reservations, from the Old server which is to be migrated
using netsh:
netsh dhcp server [ip
address] scope [scope address] dump>c:\temp\reservations.txt
2.
Edit
the exported file in notepad 'reservations.txt' , Simply do a Find and Replace
for the old DHCP server IP you ran the export on and change to the New DHCP
server IP you are importing to and remove out everything else in the text file except
for the reservations config section.
3.
On the
New DHCP server, make sure you create the new scope first, and ten just simply
run the following command DHCP server, make sure from an
elevated command prompt in 2008+(Runas Administrator):
