DNS, DHCP, FILESERVER transition from W2003 to W2008R2 DC's

[spelk]

We have a stable Windows 2003 Standard network.

W2003 DC1 on x.x.x.10 - DC, DNS, DHCP, FILESERVER

We are upgrading the network, and have a second server Windows 2008 R2 ready for insertion.

W2008R2 DC2 on x.x.x.20 - DC


For the transition, I plan to:

a) Prepare the Active Directory environment, using adprep.exe

b) Install the DC2 and promote it, using dcpromo.exe

c) Then transfer the FSMO roles to DC2.


What I need to do next is the bit I'm struggling with..

d) Transfer the DNS to DC2
e) Transfer DHCP to DC2
f) Transfer FILESERVER to DC2

g) Take DC1 down
h) Install W2008R2 from scratch
i) Bring DC1 back up as DC
j) Transfer FILESERVER back to DC1.

Since all the current workstations are looking to x.x.x.10 for the DNS, I don't know how to go about transferring the DNS. Presumably I'll have to change the DNS setup on the workstataions to point at DC2?

I think you can backup DHCP to an export file, and then import it on DC2 - but I'm not 100% sure.

I'm not entirely sure how I'm going to shift fileserving from one server and back again. The transition is taking place over a weekend, so perhaps I can just backup all the file systems, make the transition and then re-instate them on DC1 and the ACL's will remain the same.


So my questions are:

1) How do I transfer DNS from DC1 to DC2?

2) How do I transfer DHCP from DC1 to DC2?

3) Can I hold off transferring FILESERVER functionality, until DC1 is back up as a W2008R2 DC, and will the AD take care of ACL's?


If anyone has advice or help in how to go about performing this transfer and upgrade it would be very much appreciated.

Setup DC2 as secondary DNS on the local machines. (if X.X.X.10 isn't found, they move onto X.X.X.20) Create new shares, about the only way you can do for that portion. But as for file sharing, why not do a FreeNAS (Linux - Web Based) file server for sharing?! I promise it's easy to setup and use!

Also, how are you transferring your folders/groups/users/computers from the old AD to the new AD?!
What/how did you Export/Import them?! Reason I ask, is I'm ditching our Server 03 (from 2005) with AD as jefcolib.lib.mo.us DN and the new ones are jeffcolib (kiss) on Server 08 (before the old one craps out), and we have a few touchy pieces of software that have users in the AD I don't know the password to (not actual users, but software that runs on the network), so I can't just create a new user, I need the passwords to carry over.

I'm still working on my degree, as Server 08 is one of my next few classes coming up. I'm just on the antsy side, and don't want to wait for the class. So if someone whom knows a bit about Server 03 and 08 if you could help the two of us, it'd be greatly appreciated!

Hopefully things worked out for you. I've created two new DC's, all new users, gpo's and minimized but make my OU's as simplistic as possible! Just need to convert everyone to the new DC's, make two more DC's for each location, and I'm onto the next project!

Best of luck!
