  • Migrate mail stores and install 2nd Exchange Server

    Our company purchased another company a few years ago. We have been running both seperately, but now have decided to merge into a single domain structure. The two sites are connected via VPN tunnel with ISA 2004. All servers are 2003. I've already successfully used ADMT to migrate the file servers and all user accounts and SIDS into the main domain. The main site is running Exchange 2003 SP2 in the main domain. Currently the remote site has a DC that is a member of the main domain also.

    I need to get rid of the old domain controller running Exchange 2003 SP2 at the remote site. But of course I need to get the mailboxes and emails off first. I tried exmerge and that failed because of the size of the mailboxes. I can run individual PST backups and restores, but was hoping there might be an easier way.

    The second issue is, the remote site has it's own unique email domain. When I install exchange into our main exchange orginization, how do I configure it so it is only users of the remote site get the unique email domain.

    If Exmerge doesn't do it, then a manual move using PST files extracted through Outlook is your only option - unless you are moving a large number of users, then Quest might be interested in helping - but Quest aren't really interested unless you are moving 500 users or more.

    On the email address, that is simply a matter of setting up the recipient policy correctly. That means a new recipient policy, not adding the domain to an existing policy.

      I did look at quest and our 75 users didn't cut it. I was afraid you were going to say that. Do you recommend putting the new exchange server in a different adminstration/routing group. Haven't really done a seperate site with different emails on a single domain before.

      Thanks

        Separate routing group - there are benefits to do that, particularly if the other site has its own internet connection. As long as the DNS etc is setup correctly then external email can straight out and the other site can act as a second MX record site for your domain.

        Admin group - that depends if you want to restrict the admin rights in any way. An admin group is an administrative boundary, so if you have someone else on the other site who will be looking after the server, then you could use a separate admin group. Do note that you can only change the admin group at the point of installation. Once the server is installed the only way to change the admin group is to remove and reinstall Exchange. Routing groups are not subject to that restriction.
