Hello,

We are migrating our Windows 2003 R2 DHCP servers to Windows 2008 R2 Servers with netsh export/ import method. Is there a suggested method (s) to verify that the scopes and option settings are imported to its entirety.

Microsoft has the a technet article for verfication, but not a complete document from my perspective. One of the steps say to verify the scope and other settings are migrated. But how? I understand this can be done from DHCP console, but when you have 100 some scope this will be a hard task to do. Is there any way to verify the settings and scopes once DHCP database is migrated.

TIA

I think that its only possible via PowerShell script.

Actually, i usually advise to use Windows Migration Tool to proceed with smth like this.

On Technet forums there's a guide to post-migration tasks and as i said, they mention the Windows Migration Tool.

Thanks, I understand.

As the migration tool needs installing the pre-requisites and tools on both source and target servers, I prefer to use netsh method. Is there a powershell script in place to do so?

Any suggestions for this one?

TIA

Hi Tia,

I agree with you the best option for migrating DHCP server from 2003 R2 to 2008 R2 is using netsh utility.

Step 1. Export the contents using the following command on the DHCP server

  c:\> netsh dhcp server export c:\dhcpdb all

Step 2. Copy the file to the 2008 r2 where you have already installed the DHCP role on the server.

Step 3. Import the file using the following command.


  c:\> netsh dhcp server import c:\dhcpdb all
 
Step 4. Stop the DHCP service on the 2003 R2 server.

Step 5. Navigate to 2008 r2, start the DHCP service, authorize this DHCP server in AD if not and unauthorize the 2003 R2 server.

Mission Complete.

Now we need to check the functioning.

Take a client machine from the same subnet and do a ipconfig /release && ipconfig/renew.

The client will receive a IP address frm the DHCP server. Do a ipconfig /all on client machine and check the IP address of server for verification.

IF you have multiple scopes make sure that you make the changes on the switch for the Boot Relay Agent.
You have to enter the IP address for new DHCP server.


Well, the last question using Powershell Script. Powershell can be used to migrate the roles however yu need to install Migration tools on destination server and source server.

Hi,

Base on my experience, wen general use the migration tools for the complex DHCP service environment migration.

You can refer the following step by step video for the migration:

Migrating DHCP using the Windows Server 2008 R2 Migration Tools

http://technet.microsoft.com/en-us/video/migrating-dhcp-using-the-windows-server-2008-r2-migration-tools.aspx

The similar thread:

Migrate DHCP - Server 2003 r2 to Server 2008 r2

Hope this helps.

Thanks Alex.

I was more interested in the methods to compare the scope once it is migrated. When yuo have 100 some scopes, how will one verify if all the settings, server options etc. were migarted succesfully. I understand you could start comparing manually but that seems to be odd.

Thanks

Hi,
