Splitting AD and Exchange organisation into 2
Posted on 2010-09-06
Soon we will have to split our 2 Active Directory sites, and leave both running in a completely separate environment as we are selling the other business, and i am looking for the best way to do it without rebuilding the breakaway domain.
WF is the smaller site which is breaking away, and LDS is the current HQ and holds the majority of services, and will remain so.
WF currently has:
1 Exchange 2003 Backend RPC
1 2003 DC
All the Data, printers are on separate servers on each relevant site, and the user accounts are split into relevant OU's.
The Domain stuff i wouldn’t have thought would be 2 hard, as i thought i could remove the VPN between sites, force seize the roles and clean up using ADSiedit, unless there is a cleaner way of doing this.
The AD domain name can remain the same, as its pretty generic, and each will have its own mail domain, which currently resides in the Exchange 2003 organisation.
All servers are running the same and latest SPs as is Exchange.
Our current exchange setup is
Front end 2003 server running RPC over HTTPS (not in DMZ) in LDS
2 RPC backend 2003 servers (1 on each site)
1 routing group with 1default connector with the FE as the bridgehead
We will not be adding the RPC-HTTPS to the breakaway Exchange.
i have tried to get mail to route out of the WF local gateway using a new connector, but it still routes it through the FE in LDS.
Any ideas on the above would be great.
