Exchange Domain Merger

Current:

Domain 1= mycompany.net. Server 2008 domain controller, one exchange 2010 server. 800 users.

Domain 2 Satellite = Server 2008 domain controller, one exchange 2010 server

I have been asked to move the exchange server from a satellite office to my domain. The satellite office is actually the same company as mine. For some unknown reason , they have had their own separate network. They are company.org.  From my domain to theirs sits a sonicwall firewall on my side and ASA firewall on their side. We have connectivity between the domains via OPT-E Man VLANs.

I am looking for direction. I believe I can create a child domain on my domain. After that I am lost. I will need to move their mailboxes to my exchange server and still allow the network admin at the satellite office to manage his passwords etc. I am lost on the OWA SSL for both domains. Wildcard?

You cannot just add the server to your existing domain.
Therefore you will have to do a cross forest migration.

In the first instance, picking up the server, bringing it to your location and giving it its own external IP address will allow it to continue to operate as it is now.
You can then look at the cross forest guidelines. For management, you will have to configure permissions in RBAC, as Exchange works at the Forest level, not the domain.

Thanks Sembee2,

Your solution makes the most sense. I was really over thinking the issue. They have an edge server. I would down the edge server, remove edge subscription. Verify mail flow. Add DNS entry in their internal DNS so their users can find the server after I move it. Move the server to my location and create public IP's for exchange and OWA.

Thanks
