As we migrate clients from Windows 2003 to 2008 we encounter multiple situations where instead of reinventing the wheel we can leverage some nifty tools and processes... this is such an instance as we migrated a client from 2003 to 2008.
Migrate DHCP role and information from Windows 2003 to 2008:
Create a dhcp.txt file on the the 2003 server by running the following command: " netsh dhcp server export C:\dhcp.txt all "
On the 2008 server run the following command: " netsh dhcp server import c:\dhcp.txt all "
For an export and import of DHCP database for 2008 choose "netshell dhcpbackup" and "netshell dhcp restore" command (http://technet.microsoft.com/en-us/l.../cc772372.aspx)
