Moving DHCP from Server 2012 R2 to another 2012 R2 Server

A very simple process…

  1. Logon to the server currently running DHCP. It’s ok to leave DHCP running during this process.
  2. In Powershell, running as administrator: Export-DhcpServer -File C:\DHCPdata.xml -Leases -Force -ComputerName old.network.local –Verbose
  3. On the server to be running DHCP, make sure the role is installed and the service is started
  4. Import-DhcpServer -File C:\DHCPdata.xml -BackupPath C:\DHCP\ -Leases -ScopeOverwrite -Force -ComputerName new.network.local –Verbose
  5. Restart the DHCP service. At this point, everything should be transferred over.
  6. Deauthorize the old DHCP server and stop the DHCP service on the old server.
