Detailed planning and preparation is critical for a successful migration from Exchange 5.5 to Exchange 2003.

The Microsoft Visio diagrams in this download illustrate an Exchange server consolidation plan. This sample plan assumes a corporate headquarters with 10,000 users, a European headquarters with 5,000 users and a production facility and warehouse containing 750 users. The plan calls for a reduction of five servers and includes fault tolerance, with passive (standby) nodes at both the corporate and European headquarters.
