Migration and Joining of WinNT Domain to Child Domain over WAN.

[rolman]

Hi all, need advices on the followings:

I will be having a project on migrating of the WinNT branch office to Win2003 environment in New York.

What must I take note of for joining to the Child Domain over the WAN, using the 2MB Leased Line?

Here is the steps from my IT Administrator for me to carry out:
1) Pull down the child.xxxx.com domain onto my DNS server.
(I'm confused with this)

2) Setup a BDC(a high-end PC) and full-sync with the PDC.

3) Once the full-sync completed, will promte the BDC to PDC.(For Failover)

4) Then remove the new BDC task from the existing machine.
only want file and print services on this machine

5) Install 2003 on another machine and run DCpromo to join the Child domain.

6) My IT administrator will make the new 2003 DC to be the PDC master for the Child domain.

7) Both of us will create a trust relationship between the Child Domain and existing WinNT Domain.

8) I will then install ADMT to the temp 2003 DC.

9) With the trust in place and working, I will migrate the WinNT Domain users/groups and computers to the Child domain.

10) I will use the ADMT to migrate Printers, Fileshares etc.


11)After I have migrate everything, I will upgrade the existing fileserver(used to be WinNT PDC) to Win2003.

12) Run dcpromo on the files server to become a DC for the Child domain.

13)Add GC capabilities.

14) I will run DCPROMO on the temp 2003 server to demote it (Make sure DO NOT tick the box saying this is the last DC for the domain)

15)If everything is running smoothly,we will remove the trust, and take away the two temporary servers.

From the above steps, please kindly correct me if there is any steps I have overlook. OR the procedure is unsafe.

Million of Thanks
Rolman

One thing that stand out is that WinNT does not allow the removal of PDC/BDC role. A a reinstall of the complete o/s is needed in WIndows NT. You can promote and demote PDC/BDC but not remove the role.

Thanks for your advice,tubbaguts.

Correct me if I'm wrong.... Therefore I will leave the new BDC role untouch after demote from PDC. The new BDC will act as File and Print Server.

For the upgrade to win2003, I will do a in-place upgrade.

But i still concerned that pulling down the child.xxxx.com domain onto my DNS server.

Currently, my WinNT PDC is running as DHCP and internal DNS server.

This is my first time doing this type of migration. My IT administrator will be @ New York.

Thanks and Regards
Rolman

you would have to create a secondary zone on you DNS and have the NY guy allow zone transfers from the primary DNS..unless it is stored in AD. If so, NY would have to delegate your child to you and then you would create the new zone for the child.
