Migrate DHCP from 2008R2 to 2016

- On new 2016 server add the DHCP role, but do not configure it yet
- Export the DHCP configuration from the 2008R2 server.  On the 2008R2 server open Powershell (run as administrator) and enter,
netsh DHCP server export C:\dhcp-export.txt
- copy the exported text file to the new 2016 server
- Import the DHCP configuration into the 2016 server.  On 2016 server open Powershell (run as administrator) and enter,
netsh DHCP server import C:\dhcp-export.txt
- Start Server Manager, Tools menu, select DHCP.  Right click your server and Authorize
- Check the new DHCP, it should have the same configuration as the old one


The DHCP on the old 2008R2 will be deactivated automatically using this process.  You can safely remove the DHCP role from the old server at this point.
