  Hello,

  That is in case where you have performed custom changes on registry keys.

  See this document for its location: http://support.microsoft.com/kb/173396

  It is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DhcpServer\Configuration

  You can use dhcmpmig like mentioned in the article but this is not supported by Microsoft. For that, I would recommend testing that in a test environment before using it in your production one.

  In addition to Mr X  suggestion, you can check this wiki article.

  
  

  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\dhcpscope.txt
  
  Example:
        

  netsh dhcp server 192.168.100.10 scope 192.168.100.0 dump>c:\DHCPDump\DHCP.txt

  
  
  Edit the exported file in notepad 'DHCPReserv.txt', Simply do a Find and Replace for the Windows Servers 2003 DHCP server IP you ran the export on and change to the Windows Server 2008 DHCP server IP you are importing to.
  
  On the Windows Server 2008 DHCP server, make sure you create the new scope first, and ten just simply run the following command:
  

  netsh exec c:\DHCPDump\DHCP.txt

  
  
  

  Thanks

  Thanks for our help.

  Can we use netsh to export and import dhcp db instead of migration tool?

  I just checked our Windows 2003 DHCP servers and no value in these keys.  So,

  I do not worry about it.  right?

  Thank you.

  Yes.

  Since there is no custom updates, you can proceed with no problems.

  Hi Mr X,

  >since it could take one week to switch, do I need to switch to Windows 2008 R2 servers immediately after exporting dhcp db and importing to

  Windows 2008 R2 DHCP server? Can I wait for one week to switch to Windows 2008 R2 servers?

  Thank you.

  Hi,

  Why you need to import the database after a week? You can export the data when Windows 2008 DHCP server is ready. Exporting the DHCP database will contain the configuration information at this time.

  
  Best Regards,

  Aiden

  Hi Aiden,

  Thank you for your help and advice.

  When I export the windows 2003 DHCP DB, do I need to stop the DHCP service before exporting?

  Thank you.

  No need to stop the DHCP service.

  Thanks
