Why are Stage Manager customers being migrated to Lab Manager 4?
On July 13, 2009, VMware announced the general availability of VMware vCenter Lab Manager 4. Based on customer feedback, Lab Manager and Stage Manager are now unified as a single, more flexible product offering. Additionally, Lab Manager 4 offers many new features, such as ESXi support and next-generation network fencing capabilities that make this release a worthwhile upgrade for both Lab Manager and Stage Manager customers. VMware vCenter Stage Manager customers with active Support and Subscription (SnS) agreements will receive Lab Manager 4 licenses free of charge and can choose to upgrade to Lab Manager 4 at your earliest convenience.
