Move storage group from exchange server in domain A to domain B

Hello All,

I recently created a trust between two forests.  Each of the forests has it's own exchange server.  I would like to move the storage group from one exchange server to the other exchange server.  I have a stronger setup in the exvironment that I want to move the group to.  FE BE configuration with RPC over HTTP capabilities.  AD in the new infrastructure is setup to host multiple domains, however I don't really want to start from scratch for these users.  They have schedules that probably go on for months.

Question is:  Is there an easy way of moving the storage group from the one server to the other server and then just setting the users up with RPC over http and then playing with DNS.  

or

Can I setup the domain that I want to move in AD on the hosted environment and then move all of the users mailboxes to that new server.  Then, have them authenticate to the new server.  

Both exchange servers are 2003 SP2 one's running on 2003 enterprise and the other on standard.

Thanks in advance for the advice.

Let me know if any of this isn't clear.

Hi mate.
Your problem strats with the fect that you are trying to migrate exchange server(storage group) between Exchange organizations.
The only solution that i know is to export those mailboxes in to Pst files.
How many users(mailboxes) are we talking about?
You can use Exmerge ... here a nice Article about Exmerge: http://www.petri.co.il/brick_level_backup_of_mailboxes_by_using_exmerge.htm 

Hope that it will help.
Good lusck :)

I'm very familiar with exmerge.  What I would llike to know is can I export their mailbox into a pst and then import it into the new organization if I setup an account that is identical to their existing?

Do you plan to move you company address too? i mean(user@company.com).
Cause Pst file is only a Storage file for mails(if you get what i mean). the only problem that i think of is the calendar,if you want the users to get any updates for there clendar you'll have to update the MX record at you ISP DNS and then all Mails anf updates will get to the new server.

we are the ISP for the other domain.  Not too woried about MX records.  More worried about how I can get their mailboxes and information over to the other exchange server with out creating new accounts in active directory.  Think I want to do something along these lines. http://support.microsoft.com/?id=328871

Let me understand you want to use the fisrt forest(domain) (Where the old server is belonged) as Users domain, and the second forest(domain)(where you installed the new server) as Resources domain?
Can you browse the AD(where the users are sitting) from the other domain ?
Tomorrow ill try to connect one user (forest one) to mailbox that belong to another forest.(it should work)
And ill let you know.

The only way that you can do inter-forest moves is via exmerge.
Therefore the simplest way to do this is to create accounts in the second domain that match the first domain. Most crucial is the alias name.
Then exmerge out the mailboxes on the first domain and exmerge them in on the second domain.
As long as the accounts you use for the process has the required permissions in their relevant domains, you shouldn't have any problems getting the email in.

Can they then connect to their new mailboxes without using rpc over https?  What would the outlook configuration look like if the new server isn't in the same forest as their old one?

If the new server is in a different forest, then the Outlook configuration would be the same as any other Outlook configuration that is off domain. You can use RPC over HTTPS - it is just a little more complex to configure.

I've been successful in exmerging a user's mailbox from one domain into an identical account that I setup for them in other domain.  Thanks for telling me to make sure the alias was the same.  FYI.. to get the exmerge to be successful I needed to create a security group called exmerge, add the administrator to the security group and then give exmerge rights to the message store.  So again, I have two trusted domains.  I have Identical users setup in the new domain to exmerge the mailboxes into.  I have two questions.  Being that these domains are in a 2003forest level trust is there any way that I can have AD recognize the users in the other domain so that I don't have to create two users and change their password in two places from now on?  Will having identical users in the domains cause any logon issues being that they are going to have basically the exact same logon?  Thanks in advance

ShacharL,

Reading your comment from before, yes, this is exactly what I want to do.  To answer your question, yes, I can brows active directory from where the users are sitting from the other domain.  Did you ever try to simulate this?  Thanks

The setup for an exmerge account has just been covered in another question.
http://www.experts-exchange.com/Networking/Email_Groupware/Exchange_Server/Q_21853002.html

The general consensus in the Exchange community is not to use the administrator account, but to create a special account for exmerge use. That saves playing around with the extensive permission changes in Exchange.
I have a brief guide to setting up the account in my answer to the above question, but there is also a MS KB article:
