Existing 2000 AD structure to be replaced with a 2008r2 standard AD

I have a new client with a system currently running MS 2000 OS with AD, DNS, and DHCP along with file and printer sharing all in one failing box.  Typical scenario of walking in and nothing has been to the box for over 5 years and before that not much was done for at least ??.  Oldey but goody right.  Atleast the client admits the neglect and now I inherit the job of upgrading to something new.  I am up for the challenge.

Now 1 drive of the 2 in a RAID 1 config has failed and the box is ancient.  I have the system back up and running, for how long anyones guess, and the WINDOWS backups they have been doing for years will NOT restore.  Figures right.!

We will be upgrading from this OS and box to a new box and OS and our maintenance plan with DR and Monitoring :-)

I am thinking of adding 2008 in as a secondary AD/DNS and allowing replication to happen.  Once replication has happened I will then upgrade the structure to 2003 or above and then promote to be the master for the DNS.  Manual move of files and directories would be best as there was no security so we will be changing that as we go and a few custom apps with databases to move.

Never tried to go from 2000 to 2008.  Questions.
1.  will 2000 replicate to 2008?
2.  Any oddities that come up along the way that I should look for?

Found this source and it is pretty much the same process I followed when going from 2003 to 2008 several times now and all has been good in those situations.
