Complicated AD Migration

[epunk]

Hi.

Im confronted to a weird/complex AD change.

We have an AD Windows 2000 domain, say it's called company1.local, with an Exchange 2000 server for our emails.

This AD domain groups 2 OUs for 2 different businesses; company1 and acmeco.

For internal reasons, we need to seperate the 2 OU within this one single domain, create one new root domain and 2 subdomains.

Something like this :

from company1.local to

company1.common.local and acmeco.common.local.

but this implies that I also need to change the AD domain name from company1.local to say, common.local, and have the new subdomains be called company1.common.local.

Now what I'd like to know is if the following is possible:

- Creating the new temporary AD domain, say temp.local, export all users, schema info, Exchange mailboxes, etc, from company1.local to this new temp.local domain and create a bidirectional trust relationship between the 2.

- Then demote the AD servers from the old company1.local domain.
- Create the new common.local domain.
- On another server, create company1.common.local and on another server create acmeco.common.local.

- Copy back AD info and Exchange mailboxes back from the temp.local domain into the newly created company1.common.local subdomain.

From there, move the corresponding users to the second subdomain, as necessary.

Is such a scenario even remotely posible? Main concern is to maintain Exchange mailboxes and user accounts.

The above might be unclear, if you've got questions on the scenario I tried to explain, please do ask me.

Thanks and cheers.

I would leave your root domain alone. Its name has no real baring on anything that affects the outside world.

Create your 2 child domains and move your users to them and be done with it.



I hope you find this post helpful.
