EXCH 2007 - takeover email domain

Hi Experts,

I have two emails servers in two different domains.
In Domain1 I have my main exchange server.
In Domain2 I have the other exchange server with the other email domain (.info)
Is it possible to migrate the .info email domain to my main exchnage server without disturbing my existing email domain ?
Can you show me how ?

add the 2nd domain to the authoritative domains on the main exchange server and then change the mx record to point to the main domain

go to the receive connector of domain1 and add domain2 to it to receive email.

change your mx (and autodiscover if necessary) record for domain2 to point to domain1.

before you take domain2 exchange server down permanently, turn it off for a day or 2 to make sure nothing else breaks.

The above experts forgot one very important step... You need to make sure that thoes new accounts that you have migrated from Domain2 to domain1 have a Primary SMTP Address or a Secondary Alias for the old email account they had on the old Exchange Environment.

If you do not have these Email addresses in place on the mailboxes that were migrated the users will not receive any mail from the old email domain that you migrated. Steps in the correct order are below...

- point the MX record from domain2 to domain1
- create an Authoritative Accepted Domain
- Create an email address policy for Domain2 and apply this to all of the mailboxes that were migrated from domain2


Now you will have those mailboxes with domain2 and domain1 email addresses. Based on how you configure your email address policies will determine if you have domain2 or domain1 as the primary.
