Unity Builders Group (UBG) has run Exchange in a virtualized environment for a while now. They recently went through a migration to Exchange 2007 and VMware VI3, and they are extremely pleased with the results. The Exchange 2003 server was in need of a rebuild, and they needed to allocate more storage for Exchange data stores. Since Exchange 2007 was shipping and seemed to offer some significant benefits over Exchange 2003, they opted to migrate to Exchange 2007.
