Upgrading Windows 2000 Active Directory to 2008 Directory Service

Sounds like a piece of cake...
* Extend the scheme
* Bring up 2 new windows 2008 servers
* Run DCPROMO
* Configure DNS
* Move FSMO roles to new 2008 DCs
* Move DHCP
* Demote the old windows 2000 servers (then disjoin from the domain)
* Clean up in AD Sites and Services (the old servers don't remove themselves)

Well....
From the 2008 media Run adprep /forestprep
It seems to run smoothly.. almost to the end...
Then an error - a file did not exist. !!!
After a long time investigation, I turned of Antivirus... and now the scheme update ran to the end... succesfully.

Adprep /domainprep /gpprep
Adprep /rodcprep

The configuring DNS before moving the FSMO roles (using NTDSUTIL.... much easier than the GUI).

Actually - after the first hurdle, it all ran smoothly, following my steps described above...
well until I reached the DHCP..
Of course NETSH are very different from Windows 2000 to windows 2008.
So.. on the w2k box I did a NETSH DHCP Backup,
moved the file to the w2k8 box, did some editing (removed unwanted stuff, and the w2k dhcp server name)
then I ran NETSH DHCP Restore - and YES.... it worked...
