Transfer scope to new server
Export Configuration from Old Server
Open an elevated PowerShell prompt on the new server.
Run the export command to generate an XML file of your scopes and leases:
Export-DhcpServer -ComputerName "OldServerName" -Leases -File "C:\dhcpconfig.xml" -Force
Copy the exported XML file (dhcpconfig.xml) to the new server.
Import Configuration to New Server
Stop the DHCP service on the new server or ensure scopes remain disabled initially to prevent conflicts.
Open PowerShell on the new server and run the import command:
Import-DhcpServer -File "C:\dhcpconfig.xml" -BackupPath "C:\backup\dhcpbackup.xml"
Enable/start the DHCP service on the new server and verify client connectivity.
