I need to migrate DHCP from a server running 2012 R2 to Server 2019. I see there is a new migration tool however I wish the new server to have the same IP address as the old server. Does anyone have the steps or a guide for this?

Thanks.

    @Ed Dias Hi,

    Thank you for posting in Q&A!

    I've done tests in my own environment with server 2012R2 and server2019, it can be done by PowerShell command, please follow these steps:

    1.Log in with an administrator account to the Windows Server 2012 R2 system.

    2.Open Powershell and then type in the following command:

    Export-DhcpServer -File C:\DHCPdata.xml -Leases -Force -ComputerName old.network.local –Verbose

    3.Copy the file C:\DHCPdata.xml the Windows Server 2019 system.

    4.Install and configure the DHCP role on Server 2019

    5.Start the DHCP service.

    6.Type in the following command on Powershell to import the DHCP Data.

    Import-DhcpServer -File C:\DHCPdata.xml -BackupPath C:\DHCP\ -Leases -ScopeOverwrite -Force -ComputerName new.network.local –Verbose

    7.Restart the DHCP service.
    Verify your DHCP scope, IP leases, reservations etc and they should match with DHCP Server 2012 R2.

    Hope you have a nice day : )

    Thanks but your first link is dead.
    Edit: the ending ) isn't included in the link so I added it manually.

    Just reading through that guide. Isn't that for older server versions? Rather than the newer Export-DhcpServer powershell command?

    Yes, you can certainly also do via PowerShell
    https://learn.microsoft.com/en-us/powershell/module/dhcpserver/export-dhcpserver?view=win10-ps
    https://learn.microsoft.com/en-us/powershell/module/dhcpserver/import-dhcpserver?view=win10-ps

    but probably should unauthorize old, do the addressing changes, then authorize new one.
