Exchange Server 2007 Interview Question:

Should I map my current routing groups to my current Active Directory sites?

Submitted by: Administrator

Yes. Exchange 2007 is based on Active Directory sites. If your current Microsoft Exchange environment maps as closely as possible to Active Directory sites, your interoperability and migration story will be easier. Additionally, the recommended upgrade path is to upgrade all the Exchange 2000 Server or Exchange Server 2003 servers in a single routing group before you upgrade the next routing group. This lets you fully decommission a routing group as you upgrade and reduces the complexity of your current routing topology. Mapping the Exchange 2000 Server or Exchange Server 2003 routing groups to the Exchange 2007 physical topology also makes it easier to plan for an upgrade to Exchange 2007 because the two environments are similarly organized and generally correlate to Active Directory sites.
