how to join two separate domains ?

Hi Experts,

I have two separate domains in my company.
Each of them has 20 servers with SQL, AD, EXCH, TS, TSGW, WebServer, Backup Server and more.

Now the management decided to shut down the Domain2 and import all users into Domain1.

Can you show me step by step how to join both domains or how to export users from Domain2 to Domain1 ?
Also the EXCH2007 mailboxes should be exported with all settings.

I hope you have some ideas for me.

For your users, I second Kamran's suggestion.  Super easy tool and you can automate it also.  Your workstations will need to be able to see BOTH Domains during the migration.

On you exchange question, depending on how many mailboxes we are talking about, you can use Powershell to export your mailboxes to PST and then in to the new server mailbox.

The person who will carry out the import of the PST’s needs to be assigned a hidden role via the shell.  Rune the following command to assign permissions
New-ManagementRoleAssignment –Role "Mailbox Import Export" –User <username>

Then use the New-MailboxImportRequest (or export) commands

New-MailboxImportRequest is available starting with Exch 2010SP1, but we are talking 'bout 2007 here, so the Export-Mailbox approach needs to be used (requires Outlook).

How large is your company? How many users do you have? How many PCs are connected to your domain networks?

I would suggest to hire an IT company/ a consultant to do the work. There are many ways to do the migration  but to do the complete stuff by yourself, requires  a strong background and hands on experience. I do not think that any one can give you a "step by step" solutions. But yet, EE members can contribute the information that you need to know, in order to help you to do a home work for this project.

So let us know how large your organization, the number of users and client PCs etc...

Domain2 needs to be migrated to Domain1.
On Domain2 I have 250 users and 30 Mailboxes.

One advantage is, the users of Domain2 have already an AD account in Domain1, not all but most of them.
And they login to Domain2 with Terminals Services.
Zacharia KurianAdministrator- Data Center & NetworkCommented:
So your core work is to migrate all the users from Domain2 to Domain1.
Domain2 has 250 users and 30 Mailboxes.. Now a few questions:

1. Your Exchange is hosted in Domain2 or Domain 1? or do you have exchange in both domains?
2. How many member servers are connected to Domain 2? Are all the 20 servers (as per your 1st post) connected to domain2? Are all the servers physical or virtual?
3. How is the desktop of users in domain 2 are configured? Are their desktops & documents are redirected or are they kept in their own PCs?
4. Please specify the location Domain2. Is it in same building or different location? If it is on a different location how good is the WAN link?
5. You need to know if your management is willing to pay for 3rd party tools to be used for the migration.

1. I have Exch Server in both domains.
2. Domain2 has not 20 server it has 11 server, 2 AD, 1 EXCH, 3 SQL, 2 TS, 2 TSGW and 1 BACK. All physical.
3. The users are working with roaming profiles -> redirected.
4. it is the same building.
5. Yes. how much is it ?

Hi Kamran,
which tool you have used ?
With this tool I can migrate one user from Domain2 to Domain1 ?
Do I have to do this one by one or can I do this for all in one ?
