Domain collapse and reorg

Hello Experts!  I'd like some friendly advice/suggestions on how I should proceed with a domain collapse and reorg.  Here is the situation.   We were a smaller company (we will call it Alpha Company for the sake of this post) that was bought out by a larger company (Bravo Company).  Alpaha Comany consists of one corporate office and 9 other satallite offices.  There is at least one Windows 2000 domain controller at each office.  Alpha Corporate has 2 DCs.  

When Bravo Company bought us out we went though a migration phase from Domain Alpha to Domain Bravo.  Bravo Domain is much larger than Alpha Domain with multiplie sites all over the USA.  After placing temporary Bravo Domain DCs (all Windows 2003) at each site next to the Alpha Domain DCs (all Windows 2000) , we used a tool called Aelita Domain Migration Wizard 6.0 that moved all our groups and users from Alpha Domain to Bravo domain.  

Our plan now is to collapse Alpha Domain.  Since the existing Bravo Domain servers are only temporary, we would like to move their services to the old Alpha Domain DCs after the Alpha Domain collapse.  Some of our Alpha Domain servers still run services such as DHCP, WINS, and DNS, and printing that will have to be moved to the Bravo Domain DCs before we can collapse Alpha Domain.

Once all services are moved to the temp Bravo Domain servers, what would be the best way to collapse the Alpha Domain and eventually move the temp Bravo Domain servers and services over to the old Alpha Domain servers?  Thanks for all the suggestions in advance.

Hi,

Here's my opinion.

If you only have one domain, than you will only have 1 server in the corporate office (i guess) that holds the FSMO roles. Here's a good link on how to migrate them

http://www.jsiinc.com/SUBL/tip5500/rh5574.htm

Then, i would make sure to add DNS, WINS, DHCP and all other stuff to the Bravo DC (because this domain needs to be the production domain). Then, do a dcpromo on the Alpha machines, which makes DC's into member servers. Then, add it to the new domain and make sure to transfer the DNS, WINS and DHCP services.

To be honest with you, this is just the small tip and advice. There are more things to take into consideration, e.g. IP plan (which ip addresses do you use and do you need to use), how fast would you like to migrate (use the big bang or plan ahead), how is DNS set up (are all DC's DNS servers?? Are there primary and secondary DNS servers??). So as you can see, the answer isn't quite that easy..

Here is what I am thinking.

1) Gather Domain Controller roles.

2) Move Alpha Domain roles (ie: WINS, DNS, DHCP, etc.) to our Bravo Domain servers.

3) Collapse Alpha Domain.

4) Rebuild old domain controller Alpha Domain servers and make new Domain Bravo domain controller servers.

5) Move existing services/roles on existing temporary Bravo Domain machines to newly built Bravo Domain controllers that were once Alpha domain controllers.

Hi mb2010,

That's what i should do to. That's the way to go. But you don't need to rebuild the server. Just do a dcpromo to make it a member server and then do a dcpromo...

Well... The new Alpha servers (currently Windows 2000) will eventually be Windows 2003.  Does it make more since to demote with dcpromo and then run the upgrade to to Windows 2003 and dcpromo again to new Bravo domain, or does it make more sense to run a clean install of Windows 2003?

Hi,

Might be an idea. You could also do a fresh install if you think this is better for the server (might be a good idea if you don't need it)..
