Mapping routing groups

Question

Is this possible to map my current routing groups into my current Active Directory sites?

Answer 1

Yes. Exchange 2007 is depends on Active Directory sites. When your current Microsoft Exchange environment maps as closely as possible to Active Directory sites, your migration and interoperability story will be easier. In addition, the suggested update path is to update all the Exchange Server2003 or Exchange Server 2000 servers in a one routing group ere you update the next routing group. This permits you fully decommission a routing group as you update and diminishes the difficulty of your current routing topology. Mapping the Exchange 2003 Server or Exchange Server2000 routing groups to the Exchange 2007 physical topology as well creates it easier to plan for an update to Exchange 2007 because the two environments are likewise organized and generally associate to Active Directory sites.
