DHCP Migration from Windows 2003 to Windows 2008 R2

Who really wants to manually type in all their DHCP reservations into a new server? Not me, especially when you might have 30-40 reservations in multiple scopes. Thankfully Microsoft have a tool so you can backup your current DHCP Server configuration and its really simple to use too:

Source Server:

  • Ensure you log onto the DHCP server by using an account that is a member of the local administrator’s group;
  • Open command prompt and type the following command, netsh dhcp server export c:\dhcpbackup.txt all;
  • When exported, you need to ensure you stop and disable the DHCP Server service;
  • Copy the dhcpbackup.txt to the destination server.

Destination Server:

  • Log on to the Windows 2008 Server R2 as domain administrator;
  • Ensure the DHCP Service is installed, started and the startup type is automatic;
  • Open command prompt (Run as Administrator), type the following, netsh dhcp server show scope (This will show you if any scopes exist on the server);
  • If any scopes exist you will need to delete them, you can do this by typing, netsh dhcp server delete scope DHCPSCOPE dhcpfullforce (replace DHCPSCOPE with the Scope address);
  • Now we need to import the DHCP settings, you can do this by typing, netsh dhcp server import c:\dhcpbackup.txt all;
  • The final set is to authorise the Scope, you can do this in the DHCP MMC, right click the scope and select Authorize.

The summer holiday for 2009 has been planned now, myself and one of my University friends will be making our way down to Paris to start with, we will then be making our way down to Spain to watch the European Grand Prix in Valencia.
