DHCP Migration from Win 2003 to Win 2012 Including Leases & Reservations (Bonus: Create load balanced DHCP at new destination)

Greetings All,

So after reading numerous articles about the subject matter, looks like I have to skip the easy netsh method of export/import of the DHCP since I need to bring over my leases & reservations, correct?

And I need to use the server migration utility to perform the migration since it will allow me to bring over leases & reservations, correct?

Is this still applicable: http://social.technet.microsoft.com/wiki/contents/articles/7411.step-by-step-migration-dhcp-from-windows-server-2003-to-windows-server-2008-r2-with-windows-server-migration-tools.aspx?  for my scenario or is there a shorter/easier method that still brings over my leases & reservations? Will this still work if my target server's (Win 2012) IP is different from the source server (Win 2003) IP?

Also, what's a good resource for setting up load-balanced (NOT 80/20 split-scope) DHCP at the target Win 2012 server? Yes, I do have a 2nd 2012 server ready to team up with the target.

Thank you in advance!

It looks like much simpler migration steps can be found at https://support.microsoft.com/en-us/kb/962355
It covers issues with reservations.

Microsoft has a new DHCP Failover capability that allows a single scope to be served by two servers without needing to do split scope.

No need to skip standard netsh dhcp export / import method. This will bring / migrate all your leases and reservations without any issues.
I have done this activity before from 2003 to 2012 R2 dhcp server.

The dhcp migration through server migration tools is complicated and not required

Also you can create DHCP cluster on 2012 server without splitting up scopes as mentioned earlier, its easier way because anyways you already have two dhcp servers, only you need to add some shared storage for cluster

Thanks, guys! This is exactly what I was looking for.

Cheers!

DHCP Failover does not use/require shared storage. It is a new capability native to DHCP and it only requires that the two DHCP servers can communicate with each other to share information about the DHCP configuration and status.

Hi Kevin,
Thanks for the information, I am unaware with new feature, I think this is new with 2012 onwards..
