Move DHCP scope from Windows Sever 2000 to Windows Server 2003 or 2008

Move DHCP from Server 2000 to 2003 or 2008

Microsoft has detailed step by step KB article on it.. in brief.

  • Reduce the lease duration on server 2000 so the clients will renew IP and you will discover issue quicker if there are any.
  • Timing is important –> deactivate the scope on old server before you import it on the new one.

Here are the steps

  1. Download and install the DHCPExim utility on server 2000, it will not create shortcuts so access it from C:\Program Files\Resource Kit\
  2. Open command prompt and stop DHCP Service with the following command

    net stop dhcpserver

  3. Open DHCPExim.exe and following the instructions to export any selected scope data to be exported to a txt file. You can chose to disable to the scope immediately.
  4. Now on your server 2003 copy the txt file on the local drive and run the following command.

    netsh dhcp server import filepath\filename.txt all

  5. Authorize the new DHCP server
