To perform this procedure, the account you use must be delegated the following:
-
Exchange Server administrator role and membership in the local administrators group on the Hub Transport server and the Client Access server
-
Membership in the Domain Admins group and in the local administrators group to change site membership
For more information about permissions, delegating roles, and the rights that are required to administer Microsoft Exchange Server 2007, see Permission Considerations.
If you have network load balancing (NLB) enabled for your Client Access server, you must remove the Client Access server from the NLB array before you begin the procedure. If you will have NLB enabled in the new site, you must add the Client Access server to the array after you move it to the new site.
If you are using a reverse proxy server, such as Microsoft Internet Security and Acceleration (ISA) Server 2006, you must stop traffic from the reverse proxy server to the Client Access server before you begin the procedure, and then restart traffic after you move the Client Access server to the new site.
In any site with the Mailbox server role, you must have at least one Hub Transport server role installed. Confirm that if you move a Hub Transport server to a different site, the original site will still have the Hub Transport role installed on at least one computer.
In the target site, you must have at least one domain controller that is also a global catalog server and is running Windows Server 2003 with Service Pack 1 (SP1) or a later version.
