need to export dhcp database from win 2000 server to either win2003 or win2008

Hello all and thank as always for your time and expertise.
I've been handed a bldg that has some old servers.  DHCP for example is running on a windows 2000 advanced server and this server has one foot in the grave.  
I want to export the dhcp database from this win2000 server (there are many reservations, etc that I can't loose) to either a win2008 server, if possible or a win2003 server.  I have a new windows 2008 server waiting to be configured.
the win2008 server I believe is enterprise and is x64.  I guess my question in a nutshell is can I export the database to a win2008 server and if yes - how do I do it.  I know with 2003 the process involved a simple text file.  I just don't want to screw this up.  And if this is a problem, I can use 2003.
additionally, I could use hyper v and create a vm for this new dhcp server.  this is a huge bldg so please let me know what you would recommend as specs or should the server just be a standalone.  Thanks.  The help is much appreciated.

I'm going to try option number two of your links NJCComputerNetworks because that talks about migrating to server 2008.  Don't know why the author kept on saying 2003 when the article was about migrating to 2008.  I only need the scope and reservations but I'm assuming that's what comprises the dhcp database.

Hello,
According to technet link provided there is no direct dhcp migration path from windows 2000 to Windows 2008. You will have to migrate to windows 2003 and then to Windows 2008.
http://technet.microsoft.com/en-us/library/dd379535.aspx.

I suggest that you move the DHCP database to a temporary Windows Server 2003 machine, and then migrate to the Windows Server 2008 machine.
For migration check below links:
A. How to move a DHCP database from a computer that is running Windows Server 2003 to Windows Server 2008 -
http://support.microsoft.com/kb/962355
B. move a DHCP database from a computer that is running Windows NT Server 4.0, Windows 2000, or Windows Server 2003 to a computer that is running Windows Server 2003- http://support.microsoft.com/kb/325473

Thanks.

Other way to migrate a DHCP 2000 configuration to Windows 2008.

1) On the 2000 DHCP server, in a command line, use the netsh dhcp server dump > MyDHCPConf.dmp This step create a script that describe all the DHCP configuration.

2) copy MyDHCPConf.dmp to Windows 2008 server, and edit the file to replace the IP address of the origin server by the IP address of the destination server.

3) On the 2008 DHCP server, in a command line, use the netsh exec MyDHCPConf.dmp to generate the new configuration.

The leases will lost. Only the configuration will be transfer.
However, the leases are dynamic data, and will be recreates at the end of client lease.

abhijitiwaikar - are you sure your second suggestion would work.  This is a large bldg and I would be screwed if there were problems.  Thanks.

My second suggestion would work but for large environment and minimize the risk I recommend to migrate to 2003 and then to 2008.

Thank you very, very much.  The link was very good and the migration from 2000 to 2008 worked to perfection.  This migration was no small thing.  The 2000 server was literally on it's last legs and was beyond slow.  What a relief.  Thank you.
